Hello All,
I am looking for some handload feedback on the HK MR556A1. After shooting M193 @ 100 yards and getting some poor groupings, I tried some of my own 55 grain loads and the rifle shot extremely well. I was wondering if anyone else had any experience with this rifle and shot groups that performed well. What were your results with what recipes?
