Re: .338 Win Mag accuracy...

bedding can be a major problem.try the sierra accuracy loads for the 250 sbt they shoot great.in most guns the long heavy bullets shoot the best.are you trying 160 grains they may not shoot never tried them.do you know the trick where you turn the action screws and hold your fingers to see if the action rocks in its bed.after market stocks can suck if not bedded right even if they say they dont need it, thanks,keith

Re: .338 Win Mag accuracy...


Well, I took some advice from the board, and here's what happened:

Background- shortly after I bought the rifle, I had a muzzle brake installed. I decided to have it removed, the action glass-bedded, and the crown re-cut.

Turns out the "gunsmith" who installed the muzzle brake in the first place rolled the crown! No wonder the accuracy was poor! I took it to a different 'smith this time. The rifle was taken to the range on Saturday with its new bedding job and recessed target crown, and the results were surprising.

I turned in all sub-MOA groups with factory ammo, including one .65" group with Federal Premium HE 250 GR partitions. What a difference!

Thanks for the input and advice.

Re: .338 Win Mag accuracy...

I was going to ad a suggestion before you had it fixed but now I see that you have it shooting just fine.
I learned something one time that one should think about before going to do a lot work on a rifle. Replace the scope first with a different one and shoot the rifle again. Here's why; a friend of mine had a Win. 300 mag that was glass bedded and barrel floated and the thing still shot 3" groups, I told him to replace the Leupold scope with a different one and try it. Presto! That was the problem, bad scope.

Re: .338 Win Mag accuracy...

swicht the scope is perhaps the way but not sure that Leupold will be guilty !

338 Win is accurate , slow with heavy bullet but accurate .

big problem on the Rem rifle is the recoil lug aera receiver face is not square recoil lug is not flat and more often you have contact on one lug only , on small caliber forces in receiver during firing is less than in big caliber 338 WIN or new 300 ULTRA

all the big caliber I have shoot in new Remington group less than Remington in less powerfull chambering but after squaring th e receiver put a strong flat recoil lug from Holland and get lugs contact with correct headspace accuracy come back at a good level .

I think that with time quality became fair on most factory rifle , money saving is the world now accuracy is the past .

good shooting
