300 ultra mag

Re: 300 ultra mag

Alot more powder, about half again as much. The biggest downfall for the RUM is quality brass and of course barrel life. 300WSM is gonna start falling short of having much energy left as a counterpoint. Figure in the ballpark of 600 ft-lbs. Look at the 308 Baer or 300 Ackley for some alternatives, or even the 338LM.

Re: 300 ultra mag

I shoot a rum and have no problem with it at all, I do not know about the wsm but my 300 is on about the same level as my 338lm for speed and energy the bullet drop is also close but yes the rum is hard on barrels 1500 rounds is about it as far as brass there is not alot of different mfgs for it but I have not had any problems with remington brass.

Black stuff..goes in cases along with a primer and projectile. Goes bang when the primer is set off. Works great in a 6.5-284.

I'm glad to see your spellcheck and EDITING works for you.

Re: 300 ultra mag

Yep sure does. The 6.5 works pretty good for me too.

The .300 Ultra Mag

Re: 300 ultra mag

What exactly makes the barrel wear faster. When you state that a barrel life is xxxx rounds, your meaning it will no longer shoot a consistent group? Is it because the tolerances are too loose now?

Heat is the #1 culprit but the powder has a sand blasting effect on the throat as well. Look at any large caliber rifle barrel that has a high 600+ round count through a bore scope and you'll see fire cracking in the bore, it looks like a dried river bed. Large over bore calibers are notorious for short barrel life. And yes, the accuracy goes away with the barrel.

The 300RUM with a 29"+ barrel shooting the 210 grain VLD's at 3,250 makes the 300wsm look like childs play. A buddy of mine has had two of them, one factory and one custom. The longer barrels with the heavy bullets are where it's at with the 300RUM.


The 300RUM is a <span style="font-weight: bold">BAD ASS </span>cartridge.....................period
 
Re: 300 ultra mag

OK, then why the heck did you ask?
crazy.gif


But in any case the 300 RUM has a max load about 40g higher then the 300WSM. Again if better brass were available it might fit the bill. Heck, who knows, there might be some better quality stuff out there now. Anyway, I dont think you will find many ethical long range hunters relying on 600 ft-lbs of energy from the 300WSM to get the job done.

The 338 Lapua Mag might be more to what you are looking for. I have spotted for and witnessed a mule deer kill at 1800m with a 338LM Improved and it did a heck of a job. However, I would follow Dan Lilja's advice and not build one on a Remington action or a standard Remington clone for the sake of safety. Stiller makes the Predator XL and Lawton is now making the 8500, both are Remington footprints,but with 0.750" diameter bolt bodies. Guys out there with 338 Lapua Mags built on the standard Remington bolt body might get a unpleasant suprise should there be a case failure.

See the link below for the Lilja article.

See and did all that without swearing like a Longshoreman and staying on topic!

Re: 300 ultra mag

The 308 is even further down on energy then the 300WSM. You might be able to push the 210g bullets to 2500fps with a 308, but that would be on the top end of the load.
 
Re: 300 ultra mag

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: deerkllr</div><div class="ubbcode-body">So compared to the 300 ultra mag the 300 wsm is going to live longer. What about the 308 in comparison to the 300 wsm ?
</div></div>

You’re going down like a geriatric porn star but, yes, the .308 will live longer than the 300RUM or the 300wsm.
 
Re: 300 ultra mag

So how short is a "short" barrel life for the 300 RUM. If you run the long barrel, will the make any difference on the life?
 
Re: 300 ultra mag

deerkllr, I've never had a rifle chambered for it. However, I can ask a shooting buddy of mine that has had one and get what info he has. If memory serves me correctly I am thinking about 900-1000 rounds is what he got out of it. Again that was competition accuracy, your mileage may vary.

To answer your question....

You should be able to get 1,000+ rounds out of your barrel if you dont hammer rounds through it burning it up</span>

Re: 300 ultra mag

wnroscoe: thanks much for the knowledge. i am full of curiosity.
what would you consider adequate time between rounds to where i wouldn't be "hammering" them through the pipe.
 
Re: 300 ultra mag

Dang...you must be one of those guys Sarver was talking about. Mmm cant say I ever considered you a friend, so you must not be one of those "friends" I think I have. Honestly, I can't remember anyone using those ploys and tactics since the 5th or 6th grade.

Anyway...since we have to keep this on topic..geesh
whistle.gif


The basic premise deerkllr, is that for any given caliber, the more powder down the tube per round equals faster barrel wear. If you arent planning on preparing for Armageddon then a 300RUM would suit your needs probably pretty good. Heck if Armegeddon comes do you really want a case that takes 85-100g of powder and have to work from a bolt action anyway?

It really depends on the outside air temp along with several other things but, for range work with magnums I limit myself to three shot groups and let the barrel cool between each three shot group. Since the RUM use's a slower burning powder like H1000, Retumbo and or RL-25 it may take 3-5 shots, one after the other, for the barrel to heat up to a point that it's hot to very hot to the touch. You just have to check it as you go and stop when it gets hot. The accuracy wont suffer like a factory barrel though but, when it's hot and you keep hammering shots through it, thats when your wearing the throat out faster than normal. Remember, heat is the enemy when discussing barrel wear.
 
Re: 300 ultra mag

So if i build a 300 RUM, it will shoot to 1500 and make a 300wsm look bad. Next thing, my friend who has the 300 wsm also has just ordered a .416 barrett. What do you think about it compared to the 300 RUM? Will i be able to compete with it
 
Re: 300 ultra mag

Sounds like an arms race going on there! At 1500 I dont think you are giving up much to the Barrett, especially with a well built bolt rifle. Many top notch gunsmiths out there can set you up. Tooley, Baity, Springman, Dave Bruno, GAP, Gordy are a few names that come to mind quickly.
 
Re: 300 ultra mag

No matter what type of rifle you have/buy, it's all about the shooter and his skills behind the rifle and at the loading press when you go to 1k+ yards. If your building a target rifle for 1k+ yards, there's much better choices out there than the 300RUM.

If Lapua, RWS or Norma make brass for it, build it. If you can build a wildcat off of one of the three choices I gave you, build it. The 300 Ackley is probably the most popular 1k yard cartrdige out there, it's a blown out 300 Weatherby (Roy)
 
Re: 300 ultra mag

Don't worry Rob.I didn't consider you as a friend either.Believe me.

If you thought you were friend to me....you were wrong.I just stood there and tolerated ....well you.

Hey, hey, hey keep it on topic. The 300RUM.

Dont be sore a lil 6.5 beat the Hulk.
 
Re: 300 ultra mag

decisions, decisions, lets narrow it to the most cost efficient then? also one which is not going to be like packing around the barrett (32 lbs)

It's all about trade offs. High BC bullets at high velocities = happy shooter on target, sad shooter for barrel wear.

 
Re: 300 ultra mag

Well the 300WSM will have a longer life then the 300RUM, but not be the best game rifle at 1500. If game at 1500 is your, well..game, then the 300RUM, or a 300 Ackley would be the better route. The 300 Ackley load is right around 80 odd grains of powder, so you will get better barrel life. Bad news is you have to fireform brass and the dies will be much more expensive then the 300RUM brass. 300 Wby might be another option. Like roscoe says..gotta pay to play.

Re: 300 ultra mag

I just find it utterly amazing that you know absolutely what my thoughts are! I mean now that's a talent. You ought to set up a tent at a circus or something with those skills.

Come on now, how have I ever come across to you as thinking I am better then you? Because you jump me here in this thread and I, being the keyboard warrior I am ;), spouted off a few? Oh well, I guess a keyboard warrior is better then being a dialpad warrior.

Deerkllr, I apologize that you had all this crap thrust upon your thread. I hope the positive input from those that stayed on topic gave you some useful information.

Buy a good .308 as your first rifle. The Remington 700 VLS is a good start. It's a 1-12 twist and they shoot pretty good. You can learn reloading as you go and how to build quality ammo. When the barrel is shot out you'll be ready to step up to something more......well, better. Good luck.

I have a dpms ar10 now. So far just shooting hornady custom 150 sst im doing pretty good out to 500. I bought a re loading kit last weekend. I am going one step at a time.
 
Re: 300 ultra mag

from what i've been told so far on here, i'll be limited to around 850 with this gun being a gas gun. i have a leupy mk4 4.5x14x50 lr m1 caps illum. mil dot, probably over kill on the scope?

Not really. Thats just about minimum for most and just about perfect for a gas gun I think.
 
Re: 300 ultra mag

You've got a great start with good optics. Do some reading and play around with any number of ballistic calculators on the web and get an idea of what ranges you want to get and what velocities it takes to get there. Research load date from any number of reload vendors online and see what cartridge will do the job. I am guessing you already have an action with a magnum boltface that you want to use?

Me too.I got bitten by the longrange bug a few years ago.Tom Sarver at Thunder Valley has taught me alot.I still have not got into the benchrest game.I doubt I ever will.I have shot some benchrest matches at Thunder Valley.I'm just not into it.Being in the field with my rifle is more my game.

I enjoy trying to hit the target at long distance with anything.My latest rifle is chambered in .300 Hulk.I'm shooting a 240 gr.SMK with 85 grains H1000 powder.The thing is amazing to me.It helped on the learning curve for me.I have an interest in the .300RUM too.

wnroscoe-thanks!

Re: 300 ultra mag

I would strongly consider roscoe for the build you are wanting to do. He seems to have a bit of experience with the 300RUM, which seems to be the frontrunner here, and that means something. In 1k benchrest smiths are kinda known for the case they do, although they chamber many different cartridges. Baity does the Ackley, Tooley does the Booboo, Springman does the 300WSM, King does the Dasher and so forth. If you dont mind me asking, what action are you wanting to build on?

I shot my first 1000 yard targets with an AR10 and a case of 168GMM with a Mk4M1 10X.I had a great time.Shoot the hell out what you have,and get really good with it.It may be cheaper in the long run.It would have been for me.

Re: 300 ultra mag

Surgeon or Stiller Predator are two very good ones. Predator is a bit less pricey. $750 vs $1350. Stiller also has a TAC model that has a few upgrades for &775. www.viperactions.com is Stiller's website. Personal preference on your barrel. I like Kriegers and Broughtons. Have yet to try a Bartlein, but hear good things about them. Dont discount Douglas barrels either. Good pricing and a good barrel. Stocks..again personal preference. McMillan, Manners, HS Precision, etc. McMillan has some specials on its website from time to time. Jewell is about the standard on triggers. You'll want a brake if you go 300RUM, that or a good orthopedic surgeon
