My grow box was my loading station in my first thread you can still see my press is still mounted hahahahaha hand loading is the only way use broke folk can shoot hahaha The only thing i can think of that fits on a AR-15 rec is 450 bushmaster but i know there are a few more larger caliber round that fit the ar platform but to get the true savagness you need to step up to the ar-10 platform then you get into larger calibers with more case space equaling more FPS or HV i wish they would come out with a 22-250 ive had my eye out for years but no such luck next i think im going with a rem in 243 brush camo just so i can get one that shoot moa and its in full camo for under 2 grand if i built it myself i would run into the 3 g mark
