Are you shooting with a scope?
Also, both groups are string horizontally. That could be due to strong winds, but I hope not. If not, it could be the bedding of the forend.
Also have to ask: Are you checking the alignment of the bullets in your handloads?
Scope is a Leupold 3X9 I use for load developement.
Wind was light from right to left.
No on checking alignment Of bullets.
Same rest on both groups. Range has maybe a 3 to 5 foot drop in elevation over 200 yards.
What gets me the most is the drop.
My range less the cow.
My set up but not the rifle in question.
