Is it normal to have to shoot a few foulers before your rifle starts grouping well? My first shot out of a clean barrel (no fouling and almost no copper) Is 3 inches lower and 2 inches to the right of the main group. The 2nd shot is 1 inch lower and 1 inch to the right of the main group. The third shot is part of the group. This is at 200yds. My other two rifles did not do this with a clean barrel. All three are bolt action. Is this a sign of more problems to come? I've probably shot 500-600 rounds through this rifle (24" heavy barrel, savage 10fp in .308).
