RE: trouble AR loads
Thats what my dad was saying about the s/b dies...overworking the brass.The mods we did doesn't effect the neck just gets the die down closer to the webbing of the primer pocket where the ar needs the room,after what we did the formed brass comes out to the same spec as new winchester brass,they mic out at under .375.If the area above webbing is .376-.377 they will cycle under firing conditions but if you have to eject them by hand they may stick if chamber is new or tight.Sure would suck a big one to pull the head of a case that way!
