Gunsmith fixed rifle. He ran the new reamer in it.(Bullets slide in and out of fired case necks now) I loaded formerly sized brass with bullet jammed into lands with moderate powder charge(46.2grs of H4350 behind 105gr Hornady BTHP) to fire form brass to new chamber. I had no extraction problems and was able to hit most of the full soda pop cans at 430 yards in NV desert,with mild winds .
