I have a 22-243 winchester. It is a standard neckdown with no shoulder mods. Mine has a 1in8 twist and shoots a 75gr A-max into a hole. The load is 48 grs Rel 25, fed.210, 75grA-max. It flies just under 3700fps. This is a very popular cartridge in northeastern Wyoming. It is very easy to load and shoots fast, far, and flat.
