I have loaded several different loads with 3 different powders and 3 different bullets. Why do ALL of my groups string vertical and horizontal? I am shooting a Encore pro hunter 28" 7mm-08 with 120,139 and 140 gr bullets. Leupold FX-III 6X42 scope. Weaver mount,quad lock rings,Custom stock. I can put a dollar between the forend. I don't think it is touching. Could a fouled barrel do this? I have scrubbed it with Hoppes #9 Bench reast and Wipe out several times. I am kind of new to this reloading thing. Any suggestions?
