Not going to try another casting until I can get a more substancial knockout rod.
Measured the bore at the muzzle with a digital miccrometer .344 and .359.
Measured about 30 old rounds of 9.3x72R's that I have collected over the years, they are all over the map, .34 to .37?.
Reexamed and did some mearurements on the case I smoked up, it is larger by .005 at the rear of the case and that's where it's hanging up. Miller set me straight. Thanks.
What do you think about renting a 9.3x72R reamer and opening it up to the standard 9.3x72R?
