Shooting 80gr Berger VLDs out of my 22-250AI 26" 5R 8"twist BBL 42.5 grs of Re #22 produces 3350 AVG 42.5 IMR 7828 produces 3325 AVG both about the same accuracy. 1 more gr of either powder will lock the bolt up.... So which powder should I use?

Interesting how a BBL likes one powder over the other when their both slow burning powders? Why? Does it have to do with the harmonic's of the BBL ?
Just back from the rifle range. Re#22 is the stuff. Narrow ED amd SD nice tight group . IMR 7828 with same powder charge as Re#22 ( 42.5) Produced 100 FPS ED out of 6 shots.
