Hi all. I just started to work up a good load for a AR that I just got. The second load I tested gave me a 1/2" group. The first two gave me about an inch. I had been shooting cheap factory stuff to get the brass and a starting point. I was getting like 1 1/2 to 2 inch groups with it. The load consisted of 77gr Sierra HPBT over 22.9gr of IMR 4895 with Remington 7 1/2 bench rest primers. That is much better than I thought I would get out of an AR. I am liking this rifle more and more.
