crs;

I knew Bob, aka "Birdhunter" and I know your DR that he built well also. He and I had different opinions on how much over pressure to proof test a DR, I chose high pressures and he a good bit less. It was not that Bob did not like regulating, but was a bit over careful holding chamber pressures down and he regulated using loads that were lower velocity and pressure than most any other shooter would use. Therefore shooting off the shelf ammo and handloads in one of his DR was going to produce different bullet impacts at the distance where originally regulated the point of impact.
