Your winchester model 12 shotgun in 20ga was made in 1913.I should point out that the chamber of your 20ga shotgun is 2 1/2in.The winchester model 12 in 20ga was chambered in 2 1/2in until 1927.So caution is advised when shooting your shotgun!Do not attempt any modern day shotgun shells that have a length of 2 3/4in.
