Don't know the bore diameter on this particular gun but do know the throat diameters. I probably got busy & had to put it away, lol. Regardless of the bore diameter, I make bullets to fit the throats. If it won't shoot like that I'd sell it.
There are guys who will ream throats to get what they want but that seems like a pain.
That’s me all over. Once you figure what the groove requires to not lead, sometimes you have to adjust the throat a little! I love it!
