The best load will be 24.5 grains at magazine length. I hope I didn't ruin the surprise..... It isn't magic, thousands of shooters been shooting the 69 out of AR's for lots of years. The wheel just goes round and round. It refuses to be reinvented.I love mine! Never had a single issue. I've got Profire doing a ladder load of 69gr for me, so hopefully soon I'll be able to take it down to Atterbury and report on it's accuracy.
