Shots in a horizontal string!
This past Saturday I wanted to run a few rounds down the tube on my STW and was suprised to see a consistant horizontal grouping of an inch or so. This rifle has never shot like this before. Was a .5 MOA shooter with the same load from previous year. By the way this is what I'm shooting; Savage 116 action, Pac-Nor 30" SS Super Match in 7mm STW, Sharp Shooter Supply trigger and lug. Action bedded and barrel free floating in a laminated Boyds stock. Winchester brass, Fed. 215 GM, 81.0 grs. of H-1000, and Horn. 162 A-Max. Anybody out there have any idea what might be causing this.
