I posted about two weeks ago that I found 8lbs of h870 for 100 bucks. Well I finally got some time to shoot it .I started with 75 grains with a 140 berger and went up to 77.5 grains. The first group was about 1.5 moa went to 75.5 it was about 1.25 moa 76 was just under 1 moa 76.5 was about .75 moa 77 was the best .376 moa 77.5 opened back to about .75 moa. No pressure signs at all. I used federal 215 gold medal primers. Ididnt shoot them through the chronograph yet. I will next weekend. I will try to post a pic of the 77 grain group.
