338 Remington ultra mag, what your experience

A friend of mines Uncle said his Nephew just got one and it shoots good.

Hope that helps.

:popCorn:
 
i know a guy who knows a girl that said that her uncles girlfriend went to the gunstore and talked to a lady whos husband wanted to buy one but didnt have enough money so he bought a pellet gun and it shot really good.
i hope that helps.
actually there is a guy dave42 on this site and he has a 338 ultra mag and it is really acurate out to 900yrds and maybe further but that is as far as he has shot it. the problem with them in my opinion is that u can only get cheap remington brass to reload with. once again i dont own one so dave would be the one to talk to. i hope this helps a little more.
 
Having built a couple, the caliber can be fairly accurate.
The only downside is the only maker that I am aware of, for brass is Remington. Personally I think Remington brass is not the best for consistency.
The actual performance advantages of the 338 edges we build many of are not huge, but the big benefit is that Nosler makes decent brass for the 300 RUM that is the parent case.
 
Yep the rem brass sucks, I'm only getting three reloads and then they start dropping like flys as the primmer pockets give out. As far as accuracy is concerned I couldn't be happier. After doing a little brass sorting and proper load development/reloading I'm getting excellent results. 1/2 MOA at 100yds on paper and an honest 3/4MOA or better at distances up to 900yds in mild conditions. I'm shooting a tricked out rem 700 with a 30" Pac-Nor barrel.

It is a bit of a sacrifce putting up with the rem brass but it is the least expensive way to get a high energy bullet down range. If anyone bothered to make good brass for the 338RUM it would be my first choice over the lapua because it fits properly into a factory action. I even built one for a friend and got it to mag feed from a factory mag. As it is I am going to a wildcat for my next big 338.

Hope this helps.

What load are you using Dave42?
I have experienced reasonable case life, but I run my head space tight and keep my loads reasonable.

No, the Remington brass is not great, but its dirt cheap so anyone that can afford to shoot a 338 can afford to pitch the ugly ones. I clean up the high spots with a neck turning tool, ream the primer pockets and flash holes, and check for serious runout issues before and after the first firing....It takes a bit of time, but I end up with match quality brass.
My personal 338 Ultra (full on Remington) is the most accurate big rifle I have ever owned....Just luck of the draw.

Lapua brass on the other hand comes almost perfect and other than standard reloading practices I hardly even look it over....For a guy with the money, but without a lot of time the Lapua might be the best bet.

The 338 Lapua is the current fad and other than superb brass it has nothing on the Ultra. I own both and I think if money is an issue and you just have to own a 338 the Ultra or Edge is a better choice....None of the 338's are cheap to shoot...So have no illusion here.

Currently I'm on a 338 Edge trip and own 2. One is a hunter and the other is a full on long range job. The Nosler brass looks pretty good and as I have yet to fire either rifle I can't comment here....Time is a problem these days...But I think the Edge has the best all around balance, but like I said I currently on an Edge trip!

If money and time are no object I think the the 338 Lapua AI would be pretty neat...One of these days I'll try one.

In the end its all what turns your crank, but any of the big 33's generate some very cool long range horsepower....Think of them like an accurate 50 you can afford to shoot.
 
X-fan, I'm loading near the top but not to the point that I should be loosing primmer pockets after 3 firings.

I neck size only, so there should be no headspace issues unless you mean my chamber spec with respect to SAMI which is just enough to properly close the bolt on the go guage. I would bump the shoulder a thou if needed but so far my brass has not lived that long.

As far as sorting the brass and culling the bad ones I couldn't agree more. Still can't beleive some of the stuff that I have found in those green plastic bags. With a little work the brass is usable though and I have also had great results.

A close friend owned a Remington 700 chambered in 338 Ultra mag for 3 years. We developed a load for it strictly for hunting, but it was scary accurate for a big boomer. Often 3-250 Partitions would touch at 100 yards. I see no reason that it would not be great for ultra long range shooting if the correct components were used in a good tube. [Flipping thing developed plenty of recoil in a light rifle though.] Regards, Eagleye
 
my experience : 97 grains of H1000 under a 250 grain Nosler. 3070 fps and after four shots I sold the gun :wave:

:runaway:



LMAO!:D:D Well.....there is THAT little problem!


I assumed it's going in a heavy tactical rifle most likely with a brake?

Hitting at 5-600 yards with a 8.5 pound 338 Ultra takes a seriously disciplined redneck. The scope comes back at a Bubba awful quick!

Light 338 Ultras are not for everyone!
 
My gun is 15lbs without a brake and it F@#*ing hurts. One or two shots is OK but after that I'm sure the damage is irreversable:D. I feel sorry for people that punish themselfs now cause they pay for it later.

I know cause I'm one of those guys.
:slap:

It hasn't been mentioned but I would suggest nothing less than a 28 inch barrel... I have built pretty well all of the .338's from the 308 case on up to the .378 case... the Ultra Mag, the Lapua and the .378 case all need long barrels...
 
A local guy had one. I heard it worked okay. A friend had a 338 Lapua built on a PGW action. That was really cool. I shot it a couple of times.

The 338 RUM wasn't as cool.
 
the rifle I had was a LSS 700, I didnt even have it scoped when I shot it. Just fired some over the chrony for kicks. That was enough for me. Probably 7.5 lbs unscoped. I figured the extra pound a scope and mounts would add wouldn't slow it down much

Remington is pretty stupid sometimes!
The 338 Ultra is an amazingly capable cartidge that needs to be housed in a platform suitable to it's power level.

Your 7.5Lbs 338 Ultra generated the same recoil as a 458 Winchester (500gr @2100fps), but most important part is that the velocity of your rifle (the hurting part) was 25% higher than that of a 9.5 pound 458!


Drop the hot load to a more sane 3000fps, outfit the rifle in a 9 pound package, and the recoil drops from 56 to 43ftlbs.
Recoil velocity is down almost 25%.
The 8MM mag shooting a 220 grain bullet at 3050fps by comparison generates 38 ftlbs in an 8.5 pound rifle.

The vicious sting you felt at 7.5 pounds is still the real deal at 9, but nothing like you experinced! :runaway:
 
From reading this whole thread, I haven't been able to figure out if you're sheep hunting with this portable cannon or looking to reach out and touch mostly paper with a benchrest or tactical type configuration. This is important because from all of the replys, you're getting stories on both sides which is good. Brass seams to be a huge consideration though. At any rate, if you're looking for an out of the box answer to knocking down big game, I think you'll probably have to invest more money into the gun to counter and recoil. With that, maybe take a look, depending on how much you want to spend, at something that is set up to handle the recoil right off the bat. You'll probably find, like most have, that trying to fix something that was never created with much thought into shooting in the first place, is like trying to stop a screen door from letting water in by plugging each individual hole one at a time.
 
yep, it felt like a 416 Rem Mag w/ 400s. :) I now have a 8mm Mag which shoots 250s @ up to 2900 f/s but with 15 grains less powder than the 338 RUM. I will load them even less to 2750 f/s...its a handful but not bad, should be better once I swap out the walnut for a Mcmillan with a 1" decel :D
