is rl 19 very temperature stabile? If not is there any that have close to the same burn rate that is? Thanks

RL-19 is pretty temp sensitive. Say you work up a load on a cold day thats max, be careful shooting that on a warmer day. I've read differences as much as almost 100fps from cold/hot days.

screech,
RL19 is not real temperature stable. Of the powders that are supposed to be stable, Ramshot Hunter is the closest in burn rate and H4350 is not very far away. Good luck, and good shooting.

thanks guy's. I was wondering why it shot like crazy when it was summer and now I'm looking at close to the inch-inch and and quarter groups with the same exact loads.
