my friend made the mold no need to lap, the pictures show three different bullet dia. the groove is .381-,3815, the largest bullet that fits in the case is .381,Starline brass, WW is too small without reaming
OSO
actually the one that went Sideways was just over bore dia. patched .378, bore is .375.
bullet .367, patched 3 wraps onion skin, almost .002.
the first bullet shown is .374 dia.
the only thing that can be done is open the chamber up and throat it which is one of the next steps.
The last bullet that was shot I didn't put the picture up , because i'm running out of space I think.
The last bullet was patched .381, with a twisted tail, and there didn't seem to be any leading. 16/blue dot, but the cleaning patches are still torn. indicating something sharp in the barrel.
