I got back out there today. Plan was to shoot a few at 8X scope power, then at 5x then 3x, then switch ammo from Remington to Nitrex. I wouldn't believe the results if I didn't see this myself.
First shot 8x @ 100 yds. Bullseye! Next two within 1" or so of the bullseye. Scope out to 3x. All on the paper but the group went out to about 4". I understand that because I can't see the target as well. Back to 8x. Two more near the bullseye with Remington, then a Nitrex. ...7-8 inches to the left! More Remingtons, right back on! Nitrex to the left! Go figure. I woul never have thoguht there'd be that much difference.
