if you can find it, try out AR Comp.. burn rate pretty much the same as RL 15 although not the same as I am told, but close enough as I have found...
it is both temp insensitive and I actually find it even more accurate than RL 15, in multiple rifles in multiple calibers.
I've passed on RL15 I have found lately, waiting for AR Comp.
If this shortage ends, if we can manage to get the Democrats out of office, then AR Comp will be my new staple, replacing RL 15 in my powder cabinet.... which has seen a lot of RL 15 pass thru it over the years...
A lot closer to Benchmark than RL-15....in about everything all are listed in.
2-3 grain swings in data in a 223 case is a mile.
I've had good luck with it too, but its more of a sub for Benchmark, not even close to RL-15 with bullets north of 60 grains in 223 cases.
