I must admit, I am partial to the O/U's, (two shot auto's.)
My collection includes:
L to R
Stevens 311 12-gauge, (currently for sale in the classifieds) Savage 24 .22LR over 20-gauge, My first shotgun Winchester 25, My Grandpa Turks, poor man's model 12, bought used in the 20's Weatherby Athena Grade III 12-gauge 26" bbl's Red-Label 20-gauge 26" bbls. Woodside 12-gauge 28" bbl's.
I've owned "security shotguns", but sold them all. Seems like no use for a shotgun you can't shoot at a clay pidgeon, pheasant, quail, chukar, or grouse with.
If there is any proof of a man in a hunt it is not whether he killed a deer but how he hunted it.
