This topic has probably already been posted on here but this is my first time to be on this site. I live down here around berryville, ar where nighthawk tactical is out of and i have been up there to see their craftsmanship and detail to their rifles and i really like what i see. I am having a real hard time deciding which caliber to go with. I think a 300WM is a great all around round as far as reliability and the fact that they are fairly cheap to shoot. I do want a round that will still be grouping good at a thousand yards and still have enough energy to put down elk or mule deer. The 300 RUM has its advantages of not being a belted case, get more reloads out of it maybe, able to use more powder with the bigger case. I don't know anyone around here reliable enough with a RUM to make my decision off of what they know. I'm also debating on barrell length. I'm thinking 28" for the 300WM or 29" for the RUM. The barrell i'm going with is still around .750 at the crown so I'm wanting to go with a fluted barrell. Thanks for any help.

Grouping is one thing, but putting down an elk, or mule deer at a 1000 yards is another issue, certainly a controversial issue to say the least. Both WM and RUM are capable of shooting good groups, if built well by the proper gunsmith. The RUM, like you said, is going to take more powder, more velocity, burn the barrel out faster, takes longer to cool the barrel down after about three shots. In my opinion, if you want a good paper puncher at a 1000 yards, go for the 300 win mag. Hunting at a 1000 yards? Well just say that I reserve my comments to myself.
 
Re: 300 mag vs. 300 ultra mag

Don't hold nothin back. I'm not dead set with anything yet. These two calibers are just what I've narrowed down to. I'd like to have all the help i can get. If I'm going to spend this much money on a rifle I want a sure enough good one. I have a 375 ultra mag in a 700 remington so i hate to have another one but that might be something to look at too i reckon. I was also thinking that if i jumped up to a bigger caliber i would probably be giving away accuracy. Any info you or anyone else can give me would be very much appreciated.
 
Re: 300 mag vs. 300 ultra mag

What I am beginning to wonder is why shoot anything 300 mag. You are dealing with bigger recoils, a lot of people go muzzle brake, why not just blow over the top and go 338? More take down power with good ballistics at long ranges.

There are several 338 rounds. The 338 WM is not even in same league as the LM, or the RUM. The next question that you need to ask is how much is it going to cost me to shoot until I become proficient at long range? Well, with the 338 LM, it's going to cost a boat load. I have both the 300 win mag and the 338LM. I am shooting more of the 300 win mag than the bigger brother, just because of cost. If reloading properly, my 300 win mag can stay supersonic out to 1800 yards (here in my local area). Is that sufficiently long enough for you ? BTW, if you have a burning desire to get the 338 caliber, I would get the 338 LM.
 
Re: 300 mag vs. 300 ultra mag

Yes sir thats plenty far enough. It will take me quite a while and quite a bit of money to get profficient at shooting at a thousand with any caliber i go with. I have been leaning towards the 300 for just that reason, being cheaper to become a shooter with. I had a 308 that i finally got to where i could bust milk jugs at 800 yards with but it took me around three months of shooting and many rounds to do it. I like the lapua but ballistics wise i don't know that it would be worth the extra money to have it over the rum. and where i'm located sometimes it can be a chore to find lapua brass.
 
Re: 300 mag vs. 300 ultra mag

I have a .338 RUM with a vias muzzle brake - which works quite well to dampen the recoil if not the muzzle blast. It'll reach out to 1750+ before dropping sub-sonic with a 300gr Matchking, and while it's PACKED with Retumbo, I think I could pack a little more in there if needed. It still has over 1000lb's of energy at 1500yrds which isn't bad,... not bad at all
laugh.gif
I think an Elk hit at 1000yrds (1240fps, and 1700+ lbs of energy) would be feelin' it,... but maybe you want something even bigger,... I don't know.

Oh, and it's pretty accurate to,... (see pic)

338RUM_92-6_Retumbo_300grSMK.jpg


Nothin' amazing, but pretty accurate for a light rifle with a stock sporter barrel/action/trigger off a bipod with a rear bag,... not to mention ME behind the trigger
wink.gif
I haven't done all that much load development with it, but I'm sure it'll tighten up when I put my mind to it

Re: 300 mag vs. 300 ultra mag

That sounds good to me. I'm not set on any caliber yet. The rifle I'm having built is a surgeon XL long action with a broughton barrell, lenght will be determined when i select my caliber. Manners Composite stock with a nightforce 12x42x56 NXS scope. After reading some of the other posts i am leaning more towards the 338 rum. I really like my 375 rum. I have a JP howitzer brake on it loading 260 gr accubond with 96 grains of IMR 4350 behind it. Everything else on it is stock and its a great shooter to 500 yards, thats as far as i have shot it. Looks like yours is shooting very good as well. Have you tried any IMR 4350 in that round? I have had alot of luck with that powder in different calibers that i have loaded. Thanks for your input.
 
Re: 300 mag vs. 300 ultra mag

I haven't tried 4350 in it,... I don't even think I've EVER used 4350, Ive tried dang near everything else in various guns ;)I always thought it was probably too fast a burner (for short mags), but I'll give it a shot,... both figuratively and literally

Thanks for the advice!

Honestly (even though I brought it up!) I'm not the person to answer that. Cost is always a factor and we have to answer that individually.

But my thought is, everyone wants to go bigger and bigger, why not just skip a step? 338LM will be expensive for your future self also, why not just learn that gun now? You are already good at the 308, I wouldn't be convinced that shooting an intermediate gun would help you enough to justify the cost of an extra gun.

OTOH, I keep reading that 338LM is not a hunting round. I don't know ballistics well enough to tell you the whys and what fors there.

But I am thinking of skipping the 300 mags, although I am a year or two from having to make the decision, much research between then and now.
 
Re: 300 mag vs. 300 ultra mag

I have had a few 300wm 2 300rum and now I have a 338 Lapua. In my testing I was able to get much better accuracy from the 300wm than the 300 RUM.

I have not yet fired my 338 Lapua yet but I think I will like it a lot except for the price of ammo.

Mostly I have been shooting 22 because of the cost.

How much better were the groups with the 300wm? Did you do your own loads? I have heard that from several people about the lapua. The few people around here that has bought the lapua were unhappy with it claiming they could never get very good accuracy out of it but I can't hardly believe that. I've met several people over the road that said they own a lapua and another rifle and they couldn't tell me what the other one is because once they got good with the lapua its all they ever use. Thanks for your input.

I've never tried the hodgdon 4350 but the IMR is pretty good stuff. We load it in 300wm, 375 Rum, 270 and I loaded it in my 308 and usually get excellent results out of it. Its actually a pretty slow burning powder, builds good pressure, and doesn't leave as much gunk in the barrell as some of the other powders. Every rifle usually gets better results with different powders and bullet weights but you might give it a shot.

These guys are right, the 300 Win Mag has plenty of reach for even extreme shots that push the boundaries of being humane, and it is a much more popular option i.e. more components to play with in regard to brass, bullets, etc. The 338 RUM & 338 Lapua are great, but you're limited to a meager amount of options for brass and even bullets for that matter,... Plus, the components are usually quite a bit more money and you'll use more of 'em - I was amazed at how fast I could blow through a 1-lb can of Retumbo with my .338 RUM! All of them are capable of great accuracy, which is a function of the usual variables: barrel, bedding, practice, load development...etc... not necessarily in that order.

Thats a dandy buck. Great shot too. I really think I would be better off with the 300wm. My dad has one and thats the only rifle he carries. Its taken deer here in arkansas, kansas, and elk in wyoming. And he hardly ever has trouble getting brass or bullets. Did you try different loads with your rifle or did the H1000 just work really good as your first load? And I don't reckon I've heard of VLDs. Have you had good luck as far as hunting wise with those bullets? I usually either go with hornady or nosler ballistic tips or accubonds. Thanks for the help.

I think ya'll are right. Its just a really good round. Everything is about shot placement on long range shots, i think anyway, and with a good accurate round like the 300wm it would be easier on the shooter to make a good shot. Not easy but easier than trying to jump up to a bigger round to try to keep the energy higher. Thanks for the welcome and the input.
 
Re: 300 mag vs. 300 ultra mag

Another question for smokin99. If the cost for a 28" barrell was the same as the 26" would you go with it or are you past burning all your powder and just slowing the bullet down? Also the barrell has a real heavy contour to it. I think the barrell is still around .750" at the crown. Do you think fluting hurts your accuracy? I know thats a real argument and i could see how fluting would hurt the shots on a regular light weight barrell but on a barrell that heavy i can't see it having much affect on the shot. Thanks again for everyone's help.
 
Re: 300 mag vs. 300 ultra mag

You said you were buying a broughton? If so just have Tim North go ahead and flute it before he ships it to Berryville. Tim stress relieves the barrel after he flutes it. This is the same thing that they do when they contour it. It might not make much difference to have him do it, but he charges the same as your smith so why not? I run a 28" on mine. I feel like you gain quite a bit with extra length on a magnum. For instance I'm running 210 VLD's 3030 out of mine. If they try to charge you more for a longer barrel pm me, I'll send you to my smith.
 
Re: 300 mag vs. 300 ultra mag

I run a #8 Lijia with a 1:10 twist Fluted which doesnt hurt accuracy, this gun is the one I compete with and I shot that deer at 974yards. My spotter also has a 300win and he started with a 28" barrel and he cut it down to 27" then 26" and really there was no gain in fps (very little) with the 210gr Berger VLDs. So when I built my 300win 26" is what I went with and this gun has placed 1st in matches and shoots big deer too....LOL Hope this helps any more info just let me know!
 
Re: 300 mag vs. 300 ultra mag

For those who said a 300wm will do everything, go shoot a 300wm at 1k and then shoot a 338 lapua at 1k and you'll see the difference. With the lapua, a 1000 yard shot can be just as humane as a 200 yard shot. +1 on the keeping the barrel length under 26". Go to the Lilja web site and look at the test where they start with a 46" barrel and cut it down an inch at a time to 24".

I'm pretty sure the price doesn't change on barrell length. I know the guy that owns the business thru my dad, they know each other pretty well so i don't believe he'll rip me too awful bad. But yeah it is broughton by the way. I guess they're good barrells from what i've heard they are building some good rifles. Folks that have bought them are very pleased. Thanks for the info and will pm you if they try to charge more for the longer barrell.

Thanks again for the info. Sweet looking rifle btw. They can put any contour barrell on that i want and i'd like to have the fat sucker they have on a couple 308's and the 338lapua in their building. The main reason i wanted to go with the little longer barrell is because i was worried with that thick of a barrell it might look kinda stubby with a 26" barrell on it but i don't think it would. Did your spotter gain or lose speed when he went to cuttin down the barrell?

There is no doubt in my mind that the lapua would be a big difference. I've just talked to several people about them and most of them never could get their loads right to make them very accurate which they may have just had some cheap rifles too. I have met several that just absolutely love it and won't ever shoot anything else. I just think i wouldn't like having to fight to get brass for it and payin the extra money to shoot it. Its a pretty hard decision for sure.
 
Re: 300 mag vs. 300 ultra mag

I agree with DesertHK...The Rum is capable of some excellent groups if you have a good gunsmith. I'm getting 1 3/8 groups at 500 with 91 grains Reloader 25 and 210 Berger Vld's 3100 fps. "Hunting version" But I'm all for the bigger is better mentallity. I love the big guns.

Re: 300 mag vs. 300 ultra mag

Crap man they just got me talked into goin with the 300wm and then you had to say that. Lol. I may never get this rifle built. Wish i was one of those rich boys that buy 20,000 dollar shotguns i'd just buy two of three of these. I do like the 338 RUM just don't know if it would be worth the extra money in brass, powder, plus i'd have to buy the dies for it, inexpensive but the small stuff adds up. I already have a 300wm that was given to me by a good friend. Its about the ugliest gun remington ever built, model 715 which i had planned to get rid of but backed out after it actually grouped nice for a factory rifle. I don't know what to do really. I like the idea of having a bigger bullet hitting my target at a grand, as long as its still traveling fast enough to give me more energy than the smaller bullet. Ya'll just keep sending the info. i sure like to hear about everybody's success stories with their rifle.

Get a 300win the barrel will last longer than the 300Ultra and the win has better brass get some RWS, we also head shoot steel targets at 1000yards with no problem. Speed Kills your barrel give me a high BC bullet going 2800-3000fps and easy on brass. My 300win is going 2825fps,,,,and I now have 8 reloads on my brass.....LMFAO Yes the good old 300win

 
Re: 300 mag vs. 300 ultra mag

If you want to step up in the game get a 338, Ive shot and Edge, Ultra, and Lapua all out to 2100Yards with 300gr SMKs with 91-94MOA (depends on pressure) I even think we have a Utube video of it Ill check. Heres a picture of me at the 2100yard target! That group was shot with an 338Edge that KYShooter338 now owns and he just PM me the other day telling me he shot a Coyote at 715yards.....let me wipe my tear out of my eye because that gun is one shooting SOB!

Re: 300 mag vs. 300 ultra mag

This will get you thinking, here a gun I just finished about a month ago its a 7-300saum using the Norma 300brass short action shooting the 180gr VLDs which is bergers best BC bullet.... that should keep you up tonight thinking on what to build....LOL
IMG_0070.jpg
 
Re: 300 mag vs. 300 ultra mag

The top picture is my 300win it weighs 15.7lbs, 2100yard target WAS my 338Edge and it was around 17lbs if I remember correctly, last picture is my 7-300saum and its around 13lbs.....All with 5.5-22x50 NP-R1 NightForces. Win has a 40MOA base, Edge has 43MOA custom base, 7-300 has a 40MOA base,,,,,No need for zero stops when your at the bottom of your scope. These guns are not all that fun to pack around, Ill be the first to admit that and My next project is to build a 18" 260 or 6.5x47 LightWeight Deer rifle....around 10-12LBS LOL

Re: 300 mag vs. 300 ultra mag

Ya that' the one. 338-378 is more overbore than 300wm or 338 lapua so it should like even more barrel, but as you see in that test, it only lost an average of 12 to 18 fps per inch and with the 300 grain bullet the difference from 46" to 24" was around 250 fps
