Yeah, the bore diameter of the gun would factor in. As a comparison, I use a .680 Trulock choke in my ‘back-bored’ Browning. I may be shooting anything from B.B. to #4 buck, but mostly T shot.
My Benelli has a .675” choke. There are an almost endless number of load, gun, choke, & barrel combinations. I’ve never felt the need to go to the tightest choke available. I have used the two Chokes mentioned just fine with #6 Hevi-shot turkey hunting too.
