300 win mag ??

I currently shoot a built M1a. I got into reloading when I got back from my last trip to Iraq. I use LC LR brass and 175 grain bullets. I basically just did some reading and figured it out myself. I see where most folks who reload for M1a either use 168 or 175 grain.

I am currently in Afghanistan, and my welcome home gift to myself is going to be a bolt gun in 300 win mag. Still deliberating on a few rifles, but kind of have my heart set on a Kimber. I have no knowledge on the best route for loads. Looking at something that will perform well at 1000. What are long range shooters using for brass and bullets on the 300 win mag?
 
Re: 300 win mag ??

Personally I would build my own if you want to get on top of the pile in a hurry.

You could get a 7MM Rem Mag Sendero Special on 700 action and have it rebarreled to 300 Win Mag and have the action trued up while barrel is off and be much better off financially.

If you are planning on staying with this long range game I would recommend contacting Manson Precision Reamers and ask him if he still has the Ray Steele 300 Win Mag reamer. If so get one and a rougher. This is a tight chamber reamer and will give you longer brass life. That way every time you rebarrel you get the same chamber time after time.

Bear in mind that heavy bullets and slow propellant eat barrels for breakfast. You will get longer barrel life with 175s and 190s.

There is a fair amount of long range shooting around Opelika.

PM me when you get home.
 
Re: 300 win mag ??

hey I just got through testing for my new 5R in a 300wm.and the 210gn berger bt's with 76gn of H1000 are shooting great.even the rifel is shooting great for a factory remmy.and if you are a Hornady guy the 208 A-max will work great with the 210gn bullet loads you see on this site.

and so fare I am on m 6th loading with rem brass useing a lee collet die.but have made my mind up to anneal the brass after 6 loads.and might full length it but see no need to do so since it still loads with out force.but would love to be able to get some Lapua brass.but have yet been able to find any.
 
Re: 300 win mag ??

RS,

I've used Federal, Nosler and Winchester.

Nosler was made by Norma and by far the best but twice the price of WW. On 9th or 10th loading and still going strong.

Federal (no longer avail) started to case-head separate after 5-6 loadings.

Recently bought a bunch of Winchester brass (good price, all that was avail. at the time) Required a LOT of processing to bring up to my standards for 1000 yd brass, including neck turning (necks varied .011-.017!) Jury is out on this brass, waiting for mud to dry to get into my LR spot.

Any of the 208/210's should work. I use the 208's currently. About $28/100 and shoot sub-1/2 moa out to about 600 yds. Best group at 1000 is 9" in wind off bipod in soft dirt. 1000 yd BR friend swears by the 210 JLK's for his 300WSM. Claims he can't get the 208's to group (he sold me his rejects
grin.gif
) , but he shoots 4" (under 2" for 5 shots!)with his 6 Dasher, so his expectations are a little higher!

My current LR load is 76.2g H1000 on CCI 250 primers behind the 208's in Nosler brass loaded to .010 off lands (about 3.600 COAL). Gives me about 2870fps or 7.1mil to 1000 (@4000f ASL).

Call Nosler before you buy any of their brass and verify it's still made by Norma. I heard rumor they changed and it's not as good. Not verified.

Re: 300 win mag ??

Hummer - So how difficult and involved is building one?

how much less would I be looking at spending? and how hard is it to find someone to build one? The kimber I was looking at in 300 win mag is about $2600

I do not believe I have the know how or the equipment for such a task.

Sound like the 190 grain would be the way to go to save on barrels. How much difference is there in performance from a 300 wind mag shooting 190 grain to a 308 with the 175 grain?

I will give you a hollar when I return from Afghanistan, I live in north Phenix City, and Opelika is just a piece down the road.
 
Re: 300 win mag ??

Gents- thanks much for the info. I am much more educated now than a day ago. I am very new to reloading, and pretty new to long range shooting. I did an MTT sniper course in Puerto Rico when I was enlisted back in 88. Loved it, but did not have the common sence to pick it up as a hobby. I am getting some age on me now, as I now have 23 years in the Army. I think the shooting is a good hobby for me, as it is not as hard on the joints. I did submission fighting and BJJ for about ten years, and it is time to give it up. I shot in the All Army Small Arms Championships last year, and had a blast shooting the 800, 900, and 1000. Was hoping and training to shoot it again this year, but a short notice deployment put the halt on that. I should be good for next year though.

Hummer,

You got any real data on this? Not busting your chops. Honestly curious, as it may affect me...

My understanding was that the 190's running 3000+ fps were FAR harder on a barrel, than the 200/208/210's running slower.

It was also my understanding that it was not *slow* powders in particular, but rather RL22, which is often associated with the heavies, that caused short barrel life. I have noticed a vast improvement in throat erosion since I switched to H1000.

What say you?

Re: 300 win mag ??

A 208/210 grain bullet in a 300WM is the cat's meow. I still shoot the 190 Sierra Matchking in my TRG, since I have not found anything that will out shoot it yet.
If I were to start from scratch to build a rifle, I would get a Surgeon long action with mag bolt face, Manners/McMillan stock, match barrel of your choice, Surgeon bottom metal, Jewell trigger, and have a smith build it. It would be a hammer!

Also, if you wanted a very good factory rifle, look at the Sako TRG 42. They are a less than half MOA rifle out of the box. I've got 1700+ rounds down mine, and it still shoots lights out last time I took it to 800 yards.

Actually, it's the faster burning powders, lighter bullets, and faster speeds that wear out a throat faster.

Um, I have a quick question about your post. I realize the OP wants to shoot .300 winmag, so why would he buy a Remington Sendero in 7mm mag, and then rebarrel it to .300 winmag? Why wouldn't he just buy a Remington Sendero in .300 winmag to begin with, and then rebarrel it when he's ready or has shot its lights out? I do agree that when he does have it rebarreled, he should have the action trued up, etc. I won't disagree with him buying his own reamer as well. I still just don't understand why he can't buy a Sendero in .300 winmag to begin with.
 
Re: 300 win mag ??

So am I. In just over a week when I get back to the states (In Baggers at the moment) Ill be trying my hand at reloading for 300wm for the first time. So threads like this are a great help.

Don't get me wrong. I have a 300 WinMag. And I love it for what it is. But I don't shoot it as much as other guns because the barrel sure will last fast. Same bore size as a 308. But 2 times the powder down the bore. You'll start getting measurably larger groups after 2000 rounds. Your brass will last about half as long as Lake City 7.62 brass.

My favorite load for my 300WM...? 165 flat base spitzer, and 175 Bergers. I have a few 220 Spitzers loaded. But I have to grit my teeth when I shoot them. That's why I shoot the 308 more. I'm shooting the same bullets.
 
Re: 300 win mag ??

This thread is helping me out. I already have a .308 long range gun (built M1a on Mcmillan Stock, Krieger barrel...).

I am wanting a bolt gun, and figure I would go a bit bigger on caliber, with something that is more accurate at 1000.

With my limited knowledge, I figued the 300 WM would be the best route. I doubt my ability to be able to afford to feed the .338.

I am not real froggy about having to rebarrel something often though.

I just got in contact with an old enlisted buddy from when I was in the Ranger Reg back in the 80s. Just so happens that he is now into long range shooting, and happens to be a big wig at a company that produces much ammo, reloading supplies, and so on. He is advising that I stay away from the 300 WM and go with the 338, as it is the rifle of the future, and reloading stuff will double in the next couple of years.

When I finish this tour in Afghanistan I am heading back to Fort Benning. I was the Airborne School Operations Officer when I left there. WHen I get back, I am hoping to pull an XO job in either the Army Marksmanship Unit (AMU), or the XO job with the 29th battalion that runs Sniper School. This will be my last job prior to retirement. I want a job that I can enjoy, and learn a little before I get out. The AMU boys have always been helpful, and gave me much of what I know concerning relading, and shooting.

I am going to hold off until I get back until I purchase one, as my first goal is to get debt free.

Thanks for all the advice, I should know what I want by the time I get home.
 
Re: 300 win mag ??

I have a sendero in 300 (completely stock) and love it. It shoots 168 bullets well with imr 4350 and is more accurate than I am. The downside is that it is uncompensated and kicks like a mule so I don't shoot it nearly as often as I do my .308 and 223s.

As far as factory rifles go I think the sako trg is the one to buy if you have the money.

</div></div>

A Sendero that kicks like a mule with only 168 grain loads? I hope I don't come across as a jerk, but do you shoot many magnum rifles? I've always thought the recoil even with 180 grain bullets from a Sendero was quite acceptable and tame, more of a push. I've never shot a .300 winmag that was compensated, so maybe I'm just unspoiled, but I've never thought a Sendero in .300 winmag "kicked like a mule". You must not have shot many sporter weight rifles in .300 winmag that aren't comped.
 
Re: 300 win mag ??

Everyone is different tho Tomcat...

Ive had people shoot my .308 and walk away with shoulder pain, some even say it kicks hard even on an AICS!

These same people shit their pants when they feel concussion from .300win mags going off near them...

Im only an averaged size guy, with a small frame (70kg) and for me, shooting an un-broken .300winmag would more than likely translate to a memorable kick.

I think it all depends on your experience with shooting and perception.

Some people approach the beasts with fear and uncertainty and walk away with a sore shoulder. Others approach with an already accepted expectation and walk away with a smile.

You speak a great truth! Once upon a time, I spent a day at the range with my daughter. She loves shooting my .270 so much that she's taken it from me. A stud-ly gent sat down next to her with a .30-06 intending to show her how do do it right. He got into position, pulled the trigger, and got an eyebrow full of rifle scope. Bleeding heavily from the gash, he picked up his gear and left without a word.

"And that, my dear, is one reason why you must not be afraid of recoil. Accept it, put the stock firmly into your shoulder, and don't let the rifle smell fear." Lesson learned.
 
Re: 300 win mag ??

RangerS,

For serious learning pursuits out to 1K you may be better served getting a 308 bolt gun to cut your teeth on. Your M1A is certainly no slouch but they are hard to scope properly / effectively.

That being said if you still want a 300WM and are planning on shooting it seriously the advise to buy a reamer is GOOD intel. I'm unfamiliar w/ the profile mentioned but I would look into getting an A-191 (as in military ammo A191) reamer as it has a longer throat. Getting a custom stick from the git go will also be a good idea as when you need a re-barrel (and you will) the price is usually cheaper if you send it back to them that did it first. Spend your money once and wisely.

Good luck and keep yer head down.

Cheers,

Doc
 
Re: 300 win mag ??

I love my 300wm 5R rifle. I weigh 112 and 5ft 9in. Im pretty small and no one but me has shot it out of the 70 somthing rounds. Put a break on it and go to town. Recoil is not an issue for me anymore. I couldnt be happier. Also im shooting off shelf 180gr remington boat tail and 3 of 5 touch 90 percent of time. Gonna try some hornday superperformance 180 sst and then black hills 178 a-max next. Hope that helps ya

That's all right, I'm not new to the internet.

I'm a little guy and have a bad shoulder so I avoid magnums. I stick to 223, 308 and 30-06.
 
Re: 300 win mag ??

I just got into shooting a 300wm bolt gun lately. I'm very happy with it. I'd put a brake on it for sure. It just makes is more enjoyable to shoot. ( I have one on mine and I can imagine it would whip your ass without it )

I'm reloading for mine and, I'm still new at that too. I'm still fiddling with the load for mine and, I'm still tightening it up but, so far, 75.7gr of H1000 under SMK 220gr seems to shoot through one hole most of the time. ( gives about 2860fps ) After shooting the 7.62x51 at the 1000yd line at like 40moa off the 200yd zero, it was nice being up only 27moa from my 100yd zero the other day. hahah Wind sure doesn't mess with those 220s much either!!!!

I may start completely over with the bullet jammed and work a new load up.

Hey, for what it's worth, I would buy the 300wm and not the 338 unless money is no object. Last time out at the range, I was shooting my 300wm and another guy was shooting his 338LM, I had less elevation on my scope than he did at the 1000yd line.

I'm not saying that the 338LM isn't ballistically superior but, what I am saying is that I was launching my 220s faster and flatter than the load he chose for his 338LM (250gr bullets )so, if that is possible to do with a 300wm and shoot more affectively ( than the load he chose ), why spend the money on a 338LM unless you're going to take it past say, 1500yds? After that day at the range, I went away thinking, hell, this 300wm is shooting close enough to the 338LM that at 1000yds, it isn't going to be the difference in caliber that makes the better score, it's going to be the shooter.... We know that the 338LM is going to do better at the yardages at and past 1500yds but, I wasn't shooting at 1500yds, I was shooting at 1000yds.

I want to take my 300wm out past 1000yds but, I don't know of a place to do it yet but, shooting the 300wm at the 1000yd line sure is a joy to shoot if you're used to shooting 7.62x51.
 
Re: 300 win mag ??

http://www.pacifictoolandgauge.com/products/reamers/chamber.htm

I found the above link online. I see the reamer is a tool, and assume it is for making the camber a uniform size. A bit confused on this, as I assumed a custom rifle would come the correct size. Unless this is used after so many rounds are fired to keep it the specified size.

Hope someone can enlighten me on this.
 
Re: 300 win mag ??

The gunsmith that fits your barrel will/should have knowledge of chamber reamers and the correct application for your use.

In general, chambers are either SAAMI or "match", where match can mean just about anything, but in general means a tighter chamber which greatly limits the movement of the brass within the chamber. This provides greater shot-to-shot consistency.

A longer throat will allow you to shoot longer bullets as well as load longer rounds which will increase case capacity and may give greater velocity, however, some magazine fed rifles will limit how long the COAL may be and actually cause decreased accuracy because of excessive jump to the lands.

Another problem with long throats (if you load out to the lands) may be deceased neck engagement, depending on bullet configuration, COAL and neck length.

The A191 reamer will be optimized for A191 ammo (military 190g smk match), which may or may not be optimal for the round you decide to load, and whether or not you decide to be limited to your magazine length.

Find a reputable smith (lots here) and take his advice.

John
 
Re: 300 win mag ??

jrob is correct. Your smith will certainly be able to steer you into the correct direction of chamber geometry. The reason many are advising you to get a chamber reamer with your build is that you will be needing to rebarrel if you shoot a lot. Having your own reamer will cut down on the load development process on your 2nd and later tubes or set backs. The reason I suggested the A191 reamer is to take advantage of things available where you are possibly going to be stationed.

The 300WSM will save you little in the bore life department but will save you ~ 10gr of powder per load. I personally have found the 190gr SMK is about the biggest boolet that can be effectively run from that case. Much larger and the velocity cannot be maintained next to its full sized brother.

Unless you are planning to run 240's as a steady diet, get your tube twisted 1-10 and stay with 26" or longer to get maximum effect from all that powder.

Now all you have to do is figure out what stock and glass you want

Re: 300 win mag ??

I think I have a better understanding now. I appreciate both of you gents giving a little education. I knew a little about the COAL and the throat stuff, as my NM AR can not take the 80grain match ammo the AMU guys shoot at 600.

Guess I got plent of time to think it over. I have limited reloading experience, and enjoy doing it. My thought was to just buy a rifle, load and match the ammo, and shoot. I was not planning on building, reaming, rebarelling and such.

that is the great thing about all hobbies I get into. I never realize the complexity and money until I am already in over my thick head.

I think a lot of us get into this addiction this way.
grin.gif


I now know that shooting has some rather significant recurring expenses. I like to think of it like this... brakes wear out and you replace them. Barrels wear out and you replace them.
frown.gif


I have friends that buy two and three barrels at a time, because just the barrel making process (even made by the same house at a different date) can affect load workup.

Doc's comment about buying a reamer is a very good one and I'm now in the place where I wish I had. I have access to the reamer that cut my chamber (I know the smith), but the reamer has now been sharpened which changes the shape of the chamber (yes, slightly, but perhaps enough to keep my brass from chambering).

The costs do add up. Good to be honest with yourself about how much you really plan to shoot and what you really plan to spend and do the math up front (there will still be surprises).

Best of luck. Get home safe and update us when you start your project.

John
 
Re: 300 win mag ??

I assume keeping the reamer the same is due to the brass expanding to the size of your current chamber after its first firing?? Change the reamer, then the brass size can change

Would I be correct in assuming that police tactical rifles do not go this route, as they generally have to fire factory loads due to legalities?

Is the reamer route more common for competition and bench rest/ palma ? rifles than it is for tactical rifles?

Wish I had a rich old uncle that wanted to get rid of his rifles and relaoding stuff.

years ago I ventured into rasing/ training, and competiting competition coon hounds. Man did I ever sink money into that nonsence. At least a rifle does not eat and crap when you are not using it. Would be nice if you could put two together though , and get nine or ten baby rifles.

Thanks,

Correct. EVEN if the reamer was SAAMI spec., because the spec has tolerances (another SAAMI spec reamer *could* create a chamber that will require you to resize/throw away your old brass). Good example is my current barrel. We used a very close to minimum SAAMI spec reamer to chamber it. Brass fired in my factory barrel would not chamber. Luckily a FL sizing remedied this. If I had gone with a tight chamber reamer, I *may* have had to get new brass.

I read somewhere here that a guy had GAP build him a 300wm with a very tight chamber. According to him, he could not reuse his brass. At all. Apparently even small base dies would not work. I was a little surprised...

Good questions. Outside my knowledge base/level of expertise. Doc may be along any time to fill in, or you *might* consider asking those questions in the gunsmithing forum as you'll get a broader response than just 300wm guys.

John
 
Re: 300 win mag ??

My shpeal is that the minimum SAAMI chamber [.220" belt] for 300 Win Mag, 7mmRemMag, and 338WinMag is too loose for the brass made by Win, WW, RP, and FC.

I am chambering at .215" belt.

You can get around my concerns by making a false shoulder on the neck.

Re: 300 win mag ??

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: rangerskippy</div><div class="ubbcode-body">are most 300WM shooters using a break, and if so, what are the advantages and disadvantages outside of felt recoil? </div></div>

Guys I know that shoot a LOT that don't have brakes, have heavy rifles (15-17 lbs.)

My rifle, field ready, is right at 13 lbs. and that put's it in between, but I appreciate the brake. I once put 80 rds. downrange in one session from a 7.5 lb. un-braked 300WM. I'd never do it again.

In addition to reducing recoil, muzzle jump is reduced, resulting in the ability to spot shots easier. You can't explain this to a guy who only shoots a .308. There's a BIG difference, especially shooting 208/210's or heavier.

My friends/shooting partners/spotters regard it with awe/disdain/hatred, depending on where they're positioned when I shoot and if we're under a shed roof (WOW, that IS loud!) It's loud enough, that I'm looking at something like the Surefire ear protection or some other active suppression for hunting. Most times when I fire a hunting rifle, I don't hear the shot, with a brake my ears will ring for a couple days hunting w/o hearing protection.

Re: 300 win mag ??

Ranger, about reloading for law enforcement. I am not the final answer by any means, but in this litigious society, I don't know of any agency that allows hand loads for any purpose. My dinky little department won't even allow me to use them for departmental training in case one blows up and they have to pay for my medical and workman's comp. I have heard of agencies that have sniper ammo custom loaded for them, but I can't confirm that. And they are supposedly having custom ammo manufacturers load it. Seems it would be easier to just get rifles that will shoot top end factory rounds. We are currently shooting FGGM 168gr .308s here. One Rem. XCR long range/tactical, (mine, and it has been a disappointment) and three Savage rifles. The other thing is, although we require very exact shot placement, most of our engagement distances are under 200yds and frequently under 100yds, so any good sub-minute rifle should do it. We also have a tougher time with any aftermarket changes like triggers and etc. It doesn't always make sense, but what seems obviously good to you and me may be evil incarnate to some defense attorney, so we go with the safe option to limit our liability. Rather than fight it out with a legitimate reason, it is easier to say no, don't do it because it MIGHT cause a problem. Sad, no?
 
Re: 300 win mag ??

I read somewhere here that a guy had GAP build him a 300wm with a very tight chamber. According to him, he could not reuse his brass. At all. Apparently even small base dies would not work. I was a little surprised...

you can get coustom dies to take care of this but thats more $
 
Re: 300 win mag ??

Why not try a Savage 110 fcp-k in 300 Win. ? I have a 10 fcp. le 308 HS. It is a very nice rifle. I have been drooling on a 110 fcp-k . Very accurate out of the box and less than a custom.
 
Re: 300 win mag ??

I figured as much. same in the Army, as you can not modify anything. There are two very special units that can build, modify, and relaod. They are the exteeme exception.

It is nice that you can now carry your own optic. Years ago that was unheard of. Back when I was in the Ranger Reg, folks would have looked at you like a communist had you shown up at the rifle range with an optic on your rifle.

I am using my own Vortex Razor over here in Afghanistan, and it is the best tactical optic I have used to date.

I have the 110 fcp-k. Cost was a little under $800 new. My best group (6 shots) is a little under 1" @ 100 yards with handloads. For the price, with the "Accustock" and "Accutrigger", I expected better "Accuracy". My older 308 Savage in a bedded, stiffened stock shoots a little better. Also, I believe Savage has discontinued this particular model in 300WM (can't find it on their website anymore, though 308 and 223 are still offered).

To the original question, I'm using RWS brass, Hornady 208 Amax pills, and IMR 7828 SSC. The RWS brass was the only decent quality brass I could find when I was shopping last year. Lapua no longer offers it.

Stay safe.
