For me, it's got to be Varget. The amount of calibers I'm able to reload with a single type of powder really blows my mind, and the accuracy with all of them that I've tried so far has been incredible. Varget to me is just like Frank's Red Hot. I put that S&^% on everything. Please let me know if you have a favorite powder, one you have the most success with, or one you think others should try? I know there's a powder shortage, and it's hitting us up north just as hard. I've been trying to get a pound of RL-22 to try out with my 300 Win Mag for months, no luck.
