Re: what barrels would be good for a 338 lapua
I have been doing a lot of research lately on .338 barrels for my next project and have to say that I have been reeled in by the Rock 5r barrels. Faster velos from slightly undersized bore dimensions and less deformation to the bullet because of the offset 5 groove system are very interesting things to consider.
30" barrel will be fine for the standard lapua although if you go 32" then you have some extra barrel to play with when the time comes to set the barrel back a thread or two.
The 300 grain MK's only need a 10 twist.
If it's not far, it's boring.
