prdator,
Thanks for posting that. I have moved away from RL22 in the past few years, because I had seen some pretty wide swings in velocity at different temps. I don't recall the exact numbers, but it was in the neighborhood of 100+ fps.
Perhaps Alliant has changed RL22 slightly in the past few years to make it more temp stable?
Whatever the case, I may have to start using more if it now, just to see for myself again.
Thanks.
