Update
22lb. Variable Wolf spring, with stiffer firing pin. 200 gr.. Hornady 9 gr. Longshot, mag pistol primers. 1150 fps. 230 power factor.
brass ejection about 6 ft. no pressure signs. So far everything
185 gr cast at 1000 fps. runs good still cycles.
Thinking about a bushiness/bull barrel from Wilson as next step.
