After talking to Garry he asked about speeds and mentioned I’m way over . Took chrono and gun out again yesterday at 69 grn of r22 it’s going 3640fps and getting extractor marks on brass. Looking at my results I’m getting nosler max load speeds at min published load .... I’m going to try this over again and start below minimum published data and see what happens.. head scratcher for sure. I was thinking the r22 was hot but even my 4831 loads were well above published speeds . What would cause this ??
