[QUOTE="ol mike, post: 832122, member: 4683"] I read an article on Remington's site about velocity and barrel length. In the nut shell extreme velocity rounds like a 220 swift 257 weatherby etc. will lose a lot more velocity if you go from a 26" barrel to a 20" barrel. The more "over bore" a cartridge is the more FPS you will lose w/a shorter barrel. You could build two rifles alike both set to use the 308win case design -chamber one up to 358win the other 22-243 [308win. case] . Put 26" barrels on both -start taking length off 1" at a time --the 22/308 would lose a lot more velocity than the 358win. would. Mike [/QUOTE]
