My best friend and I are getting into coyote hunting. We normally use his .223 and his .270, but we're starting to mess around with scatterguns. I patterned my Mossy 535 with cheapo #4 buckshot and I'm confident out to 50yards with my factory turkey tube. He, being the one with the $ invested in a new shotgun/choke/shells. He bought a new Benelli SuperNova in 3 1/2" and a Dead Coyote choke tube. He bought a box of 3" and a box of 3 1/2" Hevi-Shot T's.
We patterned his gun at 30 and 50 yards. I believe the choke/load combo is supposed to produce around 15-20 hits in a 10" circle at 70 yards or something like that. It wasn't close to that even at 50. We tried Improved Cylinder, Modified, and his Dead Coyote choke with both loads at 50 yards, and none did very well. The best was his DC choke with the 3" Hevi shells. But even that only produced about 5 or 6 pellets in a 10" circle. We were using big pieces of cardboard and could see most of the pattern. It was just very inconsistant. I tried on of the 3 1/2'ers in the Mossberg at 50 for s's and giggles with a modified choke (I've heard some people brag on that combo) and it was worthless.
Any ideas on what he can do to achieve the advertised pattern? I suggested to him some J-B's for polishing his barrel. I'm stumped past that.
