I don't know if my chrony chronograph is off (i had the low battery message) or if these are my actual velocities. I tried 51 grains of H4831ssc with 140 grain bergers and only got 2600 fps. I also tried H1000 53.5-55.5 grains and had mv of 2600 and 2650 fps, not much of a difference with 2 grains of powder increase. I also tried a max load of re-22 and was in the 2650 range again. All of the loads were with 140 gr bergers. I had blue skies and used the defusers. I expected at least a bump in velocity with the re-22 since it was 110 degrees outside, having read about how temp sensitive this powder can be. I plan on trying again with a fresh battery but i dont know if this has any effect on the readings. Regrettably i didn't bring any other loads for other rifles that i have tested before. Any input would be appreciated.
