Powders

[Bobke]

Had mentioned powder flame temp, not burn rate, in a previous post, but think it’s worth noting again, as related to longevity of barrel and throat life, not just the typical accuracy, velocity, burn rate, flexibility of nodes, etc comments we all pay attention to. AR Comp burns about 200 degrees cooler than its primary competition, giving me yet another reason to recommend it, along with the fact it works in 223/556, 22-250, 6.5 Grendel, 6.5 CM with light bullets and 308 as well.
