I went out the other day and fired my Mossburg ATR 100 rifle. Its a 30-06 with a scope one it. I am retired army and shot expert. Well after 15 rounds it was frustrating not to even hit the paper. I was discouraged and was leaving. You see I had never fired a rifle with a scope on it. Well there was another shooter firing on a Augustan range and he had a spotter scope. I hooked up with him and with in 5 rounds I had the scope zeroed and every thing was in the black This is a picture of my rifle, mine is brown.
