I am new to this, so help me out if you can. Shooting a CVA, using 95 grains with a 250 grain sabot. I am shooting to the left about 8 inches, moved my rear sight a bit to the right, shot 3 shots all over the place at 50 yds then put the 4th shot dead on. Is it me or too much powder? I guess I am flinching some but when I shoot it doesn't feel like it.
