I am looking for a gun to shoot 1000 plus yards. Right now I am looking at Remington model 700 in the .338 Lapua. On remingtons website there were a lot of different types of model 700. Does anyone have any good recommendations? Also how does barrel length affect long range accuracy? I read somewhere that a short barrel is just as accurate because it causes less vibration? It sounds plausible does anyone have any experience with this?
