I have a rem 870 super mag its never patterned to what I thought it should --tried x full remington, tru-glo, and comp-choke.Tried every shot on gods green earth different sizes 4-5-6's. Maybe I'm expecting too much?At 40 yds w/ printable target found online (with vitals head and spine) I'm gettingabout 8-10 in spine and vital head area around eye. In entire head about 30pelletsfrom base of neck up I normally don't shoot over 40 so i don't pattern any further back. Am I being crazy to expect more,oh by the way i haven't noticed any major holes in pattern whats your opinion????
