I've loaded 100 rounds of 75 grain BTHP with IMR 4895. It's shooting 1/2 moa if I do my part. I've done search after search to see if anyone else is using this in a match load and everything keeps pulling up RL15 is the best. With these components I have to say that some five shot groups are under 1/2 moa. I've tried 68 and 69 grain bullets as well with similar results with the IMR 4895. I've only shot these at 100 and 200 yards as of now. I'll continue to load for a 24" stainless 1/8 AR. Anyone else like the IMR 4895 for the heavier 223 bullets to be used in an AR type rifle?
