So I picked up a .300 win mag Ar style rifle. So after the first 100 rounds for break in I was disappointed. Thing was all over the map. But I knew handloads would be better. After trying everything I could as far as charge weight it still only did 1.5 Moa. I figured well it was the right price so fine. Then the manufacturer even offered to swap the barrel. Huh I thought.
But as a last ditch I made a huge seating depth change. Initial 100 yard group looks promising. Now off to 300 yards to test.
H4350 and 163gr hht.
First one is as good as I could get it at factory OAl Next one is way way past book oal.
But should work. Hopefully it shoot as well at 300.
