I'm just wondering if anyone has some experience with this choke tube. I've got a 12 guage rem 870 with a 3 inch chamber. Tried patterning some shells, but it didn't turn out to good. Only got 105 hits in a 10 inch circle at 35 yards with lead #5 shot. The choke has a .665 constriction. I also noticed that the 1 3/4 ounce shot patterned better than the 1 7/8 ounce shot. I don't have a bunch of money to throw around on other chokes so can someone point me to the best shell to shoot through this choke?
