Nothing exciting. Wondering what others have seen. Since I can't put away my latest project I've measured brass from both my mini thirty and my Ruger American.
When new or fully sized brass is fired in both rifles it grows a consistent. 013. And at the case head it swells. In modern times with computer machining why would they do that.
I deal with the same thing on some Garands. I size back with a .010 over shell holder. Gives me .009 or .010 over depending on the individual piece. For .004 head space.
I remember years ago the lacquered ammo that would stick in a hot chamber if you had a pause in the blasting. (Not a blaster for years now) maybe they do that because they don't know what someone might shove in the chamber. Arms manufacturers couldn't care less about reloaders.
So I thought maybe some might give their take on this.
