I am trying to work up a load for the 180 Berger hvld in a 7mm rem mag. I shot a ladder at 660 yards and had 4 inches of vertical between 68.5, 69 and 69.5 of h-1000. I loaded up 69 grains and tested seating depth .010, .030, .050 and .070 off the lands. Tested at 300. .030 and .070 bot shot about 2.5 inches. It was fairly windy so I loaded up just the .030 and .070 off loads and tested them at 105 yds with no wind. Both shot .75 inches. The problem is I know this fun can shoot tighter. The groups show two touching and one off. It was the same for both seating depths. It happened the first time at 300 yards as well. At 300 yds there were two right next to each other and one 2.5 inches away. What would be your next step? How do I get the one round to suck in? Forgot to mention the order is 1st shot then 2nd one off and then the 3rd back touching the first. Attached are the 105 yard groups.
