I remember seeing adds for those sub cal chamber inserts in the back the "American Rifleman" years ago. I always wondered about it. As I recall, they made them for most of the popular 30 calibre cartridges.
As I load cast bullets for my 30 cal rifles, I never thought anymore about it until you posted just now. I'd be interested in hearing how the project turns out.
