I was shopping around for molds today and stumbled across a 55gr mold for .223. Sure they make bolt actions but i'm cerious if anyone has tried these out of an ar15 or really any gas operated semi auto.
i would assume you have to gas check or powder coat them but to be honest, i'm not sure about much more than that.. and even that.. i'm not sure that would be enough.
Can you shoot them at speeds that will allow the action to cycle and bullet not to totally jack up the barrel/threading?
