I've burned up more 8 Lb jugs of RL19 than I can count on fingers and toes, and I don't even want to venture a guess on how many one pounders I've smoked. I've been using the stuff in 5 different barrels, all of which were 260's (6.5-08) For year's I ran a charge between 44.8-45.2 to get 2725ish with a 140 Hornady Interlock, Speer Hot-Cor, Partitions, or Sierra MK's. I never noticed it to be tempeture sensitive, or vary a great deal from lot to lot.
Maybe it does in other calibers??
