probably "a lot of us" out there are in the same boat.
12 gauge, check
but in my case, it's a 1949 M37 with poly choke
my grandpa taught me to shoot and hunt.
And to flip my world upside down, just this week, my father-in-law gives me 4 guns for Christmas. I was flabbergasted. 3 of them were his fathers and the other was his when a youth. I am anxious to try a few out soon, and the first will be a Ithaca double barrel 12 gauge when pheasant comes back in!
