I had a 42 Winchester, traded away years ago. Very nice gun. I have had two Browning Citori 410's. Right now I have a Browning Cynergy Feather that has 20/28/410 3 barrel set. I also have a Stoeger 410 SxS Coach gun with 20" barrel's. I had a model 12 Browning in 28ga, sold it. I have a model 12 12ga and 16ga right now. Love them model 12's and A5's. Have a Belgium Mag 20 and a standard 16 in a A5 right now. Looking for a nice vent rib Sweet Sixteen.
Note, I have shot a lot of Grouse with a 410 O/U. shot my first Rooster with a Savage 410/22 O/U. Shot a lot of ducks with a 410 also, years ago of coarse. I bought 4 boxes of federal 410 steel a few weeks back. I plan to hunt ducks a few days with my Cynergy feather with the 410 barrel's.
Enjoy your model 42, they are a sweet heart
