Guns, Dogs and Blades QnA

I do not use Bullseye powder for that very reason. You can get a double charge and never see it. For handgun I typically run Unique powder. Slower burning and a bit dirtier but if I double charge the case overflows. Not say I have not used Bullseye because I have, it is great powder but it spooks me a bit!
My boss was a reserve Sheriff Deputy, he reloaded a lot. Had a turret press. Well the turret press double charged a few one day and it went unnoticed. Our scale master had a brand new .357 Mag Ruger DA revolver and they went to the bottom of the quarry to have some shooting fun. Well, she got one of those double charged .38 specials, brand new Ruger pretty much exploded in her hand. Luckily she was not injured.
