Allen.. That load is for a 223 with normal pressures. Varget is a little slower burning and I think you will find it works well esp in an AR 5.56 the 5.56 allows much higher pressures than a 223 mainly because the chambers are slightly different with a little longer throat in the 5.56 rather than a 223. You may need a 7 inch twist to shoot that bullet. It is a long one and may be a bit slow for a 9 inch twist unless the velocity is at the top end. My rifle does not shoot them well. A guy gave me a few and I loaded them but with a different powder. They just seemed to wander around a bit. My Varminter with a 9 inch twist shoots the Nosler 69 gr match bullets very well. That is the heaviest bullet I use in any .224 size rifle. I got a bunch of blems for a really great price and they work well. I also shot some out of my 22-250 last week. But it has a 14 inch twist and did not shoot them great.
