Could anybody let me know plus's or minus's on reloading my own ammo for my AR-15? I would like to target shoot alot with it, and also I use it for deer hunting. with 64 grain power point ammo 223 I shot a big doe this past gun deer season dead run broadside shot at 70 yards. 1 perfect shot was all it took placed right behind front shoulder mid section. ran ? 40 yards before down for the count. Anyway, I paid $19. for box of 20 count for those. And I can get wolf brand 223 55 grn. fmj for $4. per box of 20 count. What would be plus's or minus's of reloading my own, or would there be any benefit? Cost of reloader, powder, but I can get then whatever bullets I want? Also, does the 5.56 come in sp to be able to use for whitetail deer hunting here in Wisconsin? What are the differences between 223 and 5.56 ammo, ballistics, or whatever? Thanks for the time and input. Semper-Fi ! to my fellow Marines ! OOH-RAH !! Oh, If positive feedback for reloading, some good links to sites to get reloading supplies at lowest cost please.
