A few pics of my Model 12 20-gauge straight gripper, 28" Nickel Steel, solid rib, Full choke, weight 6-9. Made in 1927.
She came to me with a headspace issue and resulting extraction problem. A replacement chamber ring had been improperly fitted, supposedly by a well known gunsmithing firm. Those familiar with Model 12's know the ring must be absolutely dead nuts concentric/sized to the back end of the chamber, and this one was was off. Normally that's done with special tooling from the muzzle end, but a NOS unfitted chamber ring and improvised setups on the lathe and mill did the trick here.
I shot her for the first time a few days ago, 42/44 on Super Sporting clays. She fed and extracted perfectly with a mix of Remington, Federal and Estate factory 7/8 ounce loads. All with modern steel base hulls that often cause problems in Model 12's. Ready to rock on!
There are some small raindrops on the Winny in these pics.
