I, too, want to thank those who contributed to this thread. I have contemplated trying Leverevolution powder with heavy bullets in .223/5.56 and was able to pick up several pounds on sale for $19.95 a couple years ago. It does work great in my son’s Winchester Model 94 in 30-30, but I have wondered if it would run in the AR’s. I have a good supply of TAC, which is my favorite for the .223 for both gas gun and bolt with bullets from 50 gr and 55 gr in the bolt’s 1 in 12” twist and up to 69 gr in the faster twisted AR’s. For the 40 gr tipped bullets in the bolt, I have settled on Benchmark, using Nosler’s top load.
I might just try some of the LVR with some 77 gr BTHP’s just to see if they perform any better than TAC or 8208XBR. This thread gave me some good places to start.
