Buddy helped me load my first 223 rounds today. After having shot PMC for 6 months, grouping 1.25" on average, I was hoping to see an improvement. My buddy is getting consistent 0.5 MOA with 24.2 grains of varget and 77 matchking molys, the same bullet and powder we used today. We both are shooting Barnes Precision ar15's. But in three powder weights, my gun would not best 1" groups with it, some more like 1.5". I got 4 pounds of varget this morning at LGS. Guess I need to try some other bullets. Any suggestions. 1:8 twist 16" stainless Montana barrel. We both shot mirroring groups with the 3 test rounds and our results were near identical. Looking for accurate 100-300 yard round. Any ideas?
