I shoot a 12ga, 3in.,4 shot 1 7/8 oz. pellet, I patterned yesterday and was satisfied with 20-23 bb's in the head and neck area at 30 yards. Always have had a standard that in the 20's is goodand have taked 8 birds with that theory, even a couple at 45 yards. Good Luck, be ready for a sore shoulder!!! Took me 10 shots to get me scope and pattern the way I wanted it!!
