I decided to buy one more keg of rifle powder just in case. Most of the normal AR stuff I use is out so time to try something new.
Widener has some Alliant powders that I have no experience with, 1200-R and 2000-MR. There is very little data on the 1200-R nothing over 55grs. 2000-MR has a bit more but nothing under 69grs.
Or maybe just try some AR-Comp for $20 more.
Anyone have some experience with any of them?
