Are the Alliant RL series of powder known to fluctuate much between lots?
I have heard of Varget doing this but new to RL. I had a load worked up for 7-08 and ran out of RL19. The new can loaded to same weight is giving me almost 100 FPS SLOWER? ??? I went from 2830 avg FPS with a 140 grain bullet to 2715 avg with same primers, cases, bullets, just different lot of powder.
I have RL 15, 17, 19 and the Alliant book shows 19 being faster in this cartridge
Was disappointed as it was a a compressed load and I can't go up. It was also shooting pretty nice in the rifle.
What other powders are known to do this?
