I am following. Bought a Franchi that I want to love but fine myself way less accurate with compared to my Benelli Nova. I think I am missing low
Yo ho, yo ho, to the patterning board you must go!
Patterning is VERY interesting. First, because as you suspected, no all shotguns don’t shoot the same. And secondly, it’s amazing how different shotguns shoot from shooter to shooter.
And also, chokes don’t even shoot consistently, so one brand’s modified could be closer to another brand’s full. I had this happen with a new shotgun for my son, he shot the full first and it was like a super full turkey choke. It was really, really, really tight. His IC from this maker shoots like a modified, but we have another shotgun, same brand, same chokes and it patterns completely different.
I help at the patterning board for the HS trap team and we run every kid and his/her gun through the patterning to see and show them the pattern density and COP. There’s been some pretty wild results because every person, every gun, and every choke is different.
