I mostly shoot a 1865 Westley Richards 10 bar in wood field 10 with 27" brls, it must have went back to Westley since it has newer style hammers that are rebounding but still has the 1/2 cock hammers feature. Nice gun out of a duck boat. Also have a Charles Daly 10 hammer with reverse chokes. In 16ga H Burgsmuller Dam hammeer underlever, Ferlach guild hammer, and a Lefever hammerless Dam gun. Hopefully by next season I will have 10 Scott Dam with some tighter chokes. Had to find some brls since the ones on it had a crack where someone had filed a dent.
I have been shooting Long Shot out of the 10s with #5 bismuth shot. There is a guy not far from me that makes busmuth shot. I do shoot some steel thru a hammer Husky underlever and a Beretta 10 for snow geese pass shooting.
