[QUOTE="TBuckus, post: 918939, member: 49491"] I was told once as a rule of thumb that you lose 30fps per inch of barrel. So the 100fps as stated previously is pretty close. I never heard about the shorter barrel being stiffer idea, but it makes sense. As far as reloads, I use the Lee 3 die set with factory crimp. Not an expensive set but it works. I use a recipe for Hornady 55gr FMJ and BTSP with IMR 4895 with good results. I'd have to go look it up to see the exact accuracy, but I have been happy with it since it is a plinking and close range coyote gun. I don't know the speed yet, since I just got a chrono and haven't had a chance to go out yet. I have only used 4895 and Varget, since I can't find any of the other popular .223 powders. As far a bullets, accuracy dropped when I tried weights below 55gr. [/QUOTE]
