The rifle comes in .308win, but i want to go for a .338 win mag The rifle down below is what im probably going to order, after a while because im still looking at other custom mades. I want to take it out for BIG game hunting, including Brown bear and elk. I know a .338 would work fine on either. The Crusader My question is: GAP is known for its accuracy, all the way from FBI's to hunters to target shooters. However if i wanted a re-barreling job, would it mess with the accuracy? >it has a 3/8 MOA guarantee, would rebarreling still hold the 3/8 MOA gurantee or would it change it to 1/2 MOA or something? ---it says "other calibers special order" so im guessing it wont mess with the accurcy too much...if at all. Thanks!
