In 223, unless things have changed, in the AR, if you run it to top levels, the primer pockets open since its too soft.
Take your max load and back it off 1 to 1.5 grains and you generally will do fine, that doesn't compete for many in the end though.
And I"ve seen more than a few primers fall out of factory gold medal match ammo on the first firing in an AR
Maybe they've changed it.
Maybe you have some made to LC specs but overrun and stamped FC>
I"m a brass hoarder.... I"ve never saved FC 223 as bad as I want to. I tried it a few times and it was not worht the effort so would trade it back to military for once fired LC, as all they needed was brass weight to get more ammo....
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
