338 win mag barrel length and rifling

[charver]

just need some info here guys,am thinking of getting a new barrel for my 338 win mag and was wondering what length of barrel and a 10 or 11 twist rate.

i will be shooting 225 grain with a view of going to 250grain bullets.

any advice would be welcome as im sure it will save me some pennys

cheers guys

Personally I went with a 10 twist to be able to shoot the new Cutting Edge 225 and 252. They say the 225 requires a 1:10 to stabilize.

I should have the rifle next month and will post how it performs.

Others may disagree, but I prefer a minimum barrel length of 26" on any magnum round!

If you're going to be shooting heavy bullets in your 338, I would opt for a 1:10" twist, anything slower may not give the desired results. A slower twist may be OK for light bullets, but not the best choice for the heavies.

Are you going for a S/S or Moly barrel?

Cheers.

Get a 1-10 twist and shoot the 225 grain Cutting Edge bullets D-62 I think .64 BC. The maxx ones anyway. Then you will have a 1000 yard hunting rifle for large big game. I have had excellent results with this bullet so far in numerous 338 rifles.

The good about choosing the Tikka is that is only comes in a 1:10 twist. You'll be set.

Bullet stability depends on many factors. One that hasn't been mentioned here is air density.
Air density is a function mostly of temperature and altitude. While I agree that 10" is the "normal" choice, you might want a faster twist if you shoot in arctic temperatures near sea level or could use a slower twist if you only shoot at a mile elevation in warm weather (like I do). It's better to err on the side a faster twist rate as over spinning will have less detrimental effect than under spinning.
