Re: advice needed
I just read that Alliant came out with a new powder. It's called AR Comp. It's a re-manufacturing of RL15 to be a lot more temp stable. They tested it from -20 to 120 degrees with only a 20fps change. They tested it in 223 in a 77grn bullet and .308 in 175grn bullet. They said it is closer to the Varget in burn rate. When they start putting it out, I may try some.
