I have a 28ga SXS.....maybe 10 shots thru it and like new( i bought it new so have the box and 5 chokes etc). I bought a 20ga SXS to match my 12ga SXS. PM me with a number I can send pics to if interested and I will take a few and send them.
I have a very mint Franchi 48 AL 20 ga, shot less than 4 boxes of shells over its lifetime. I bought it new & haven’t gone pheasant/chukkar hunting more than a day a year since.
