I have 52 shotguns! I have NEVER, EVER patterned them. Or any of the 150 or so I’ve owned. I have 4 with adjustable ribs and combs. I “pattern” my new gun on low 7 at skeet. If I smoke the target, no adj needed. It doesn’t show me any percentage, but works for me. I shoot about 10,000 targets a year currently. Start the criticism!
