[QUOTE="big johnson, post: 2214968, member: 116259"] I've seen several 257 ai that were cambered to long in the throat and factory ammo won't even fire, the whole case moves forward when the firing pin strikes the primer, not good. we pulled the bullets and moved them into the lands then they worked fine. Remember that all reamers are not exactly the same and can vary several thousands. New brass will work the best .If you can find the 257 roberts +p ammo it's a little hotter and works better. You can use 7mm mauser brass and neck it down to 257 or 6mm rem. and neck it up. 6mm has been showing up at several suppliers. Good luck It's a great cartridge. [/QUOTE]
