I'm temped to buy one, but wouldn't you have put the insert back in EVERY time you took a shot? Tedious at best.

yeah i think you would but it sure would ge cheap to shoot, also keep a brass rod with you when your shooting it because your goin to have to knock the case out of that insert everytime
