My 16 gauge Valmet O/U. It is choked C/F, is light weight (around 6 pounds) so it is easy to carry all day long, and is one great upland bird gun. For skeet and sporting clays, my Browning Citori 12 gauge w/ Briley choke tubes.
Don't make fun. NEF pardner .410 I inherited from my grandpa. Small, light, fun. Many memories of him over ventilating window screens shooting at red jimmy squirrels. He developed a hatred for them when they stripped the wiring on his lawn mower. Copper prices must have been up. He bought window screen by the roll. Boy my grandma used to get pi$$ed at him.
