100% chokes matter. I just got back from SD. Took my Beretta 20 ga O/U. I had carlson’s IM/M chokes in the barrel. Missed a few the first day of hunting. The owner of the land we hunt on said, you need to go tighter on your chokes. I was hesitant since I thought those would work. But I thought about it and decided I should do what he says for at least one day. I didn’t have anything tighter with me, so I went to Cabela’s in Mitchell to pick up some chokes. got a factory IM and Full (they had “returned” factory cokes for $5 each). With those in, I was hammering birds. Chokes make a huge impact on your shooting. I’m getting ready to get a Browning A5 sweet 16 and I’ll have a Trulock or Briley IM in next year (to start with). I’ll have a Mod at the ready, just in case.
