I was shooting my Model 10 in .308 today and something weird occured.
A little history first...I replaced the factory plastic stock with one from Bell and Carlson, it has a one-piece scope mount and heavy-duty rings topped off with a Nikon Buckmaster 6x18 mildot scope. With 45 grains of Varget behind a 168 Sierra Matchking bullet, this set-up is placing 3 shots into one ragged hole at 100 yards.
When I was shooting it today, 3 shots went into one hole. I then loaded 3 more rounds into the magazine and took aim on the same spot. However, the point of impact shifted about 2 to 3 inches to the right on the next shot. The next two shots were in the exact same spot using the original aiming point, making a ragged hole again.
Has anyone ever experienced anything like this before?
