Early Model 12 16 ga (1916 chambered for 2 9/16" shells) with ejection port at 2.43". Is the only needed alteration most likely to be lengthening the port? I measured an early 12 ga (2 3/4" chamber) and that port is 2.612". So both of the ports are shorter than their respective (fired) case length. Thanks! Gil

My guess, as I own and shoot 7 Model 12's- ranging from a skeet grade M12 28 gauge to several 3" Mag 12's-- the plastic hulls didn't really get rolling until the late 1950's, from 1912 to about 1957- paper hulls were the norm- and the softer opened up crimp folds most likely cleared the front radius of the receiver ejection port when the gun was cycled. The oldest M12 I own and shoot is a 1921 mfg. field grade 12 gauge 28" full plain barrel nickel steel (same analysis basically as the later Winchester Proof Steel-that was just another marketing ploy by WRA--) and it has 2&3/4" chambers-std. for the 12 gauges since 1916--
A hunting pal has a 16 gauge field grade made in the same time frame as my 12 nickel steel M12- no chamber length marked, he shoots Federal 16 plastic hulls in it all day long, no problemo.

I just treat my first year model 12 16ga just like I do my short chambered SxS's and shoot RST's in it. I see no reason to alter the gun to have it usable & effective.

Unless I am mistaken ( I often am), the Brownell book has instructions for conversion to 2 3/4", together with procedures for conversion of the Browning Auto5. Mike

Ive seen 16 gauge model 12s that had the conversion still act fussy with 2 3/4 ammunition. The stuff produced today is contemptibly cheap, especially in 16 gauge, which, seems like an afterthought to most ammunition manufacturers. Dogon is right. Just leave it be, and step up your ammunition.
Best, Ted

the plastic hulls didn't really get rolling until the late 1950's, DuPont (Remington & Peters) began offering their plastic SP shells in 12-gauge in late 1960. By 1962 they had added 10-, 16- and 20-gauge plastic shells. The Olins (Winchester & Western) introduced their Super-Speed and Super-X in "Compression-Formed" and their Ranger and Xpert in "Poly-Formed" in 12-, 16- and 20-gauges in 1964.

The current length of the 16 ga hull is quite variable. Remingtons are usually the shortest. and Fiochis on the longer end. The softness of the hull and how forcefully you work the action can make a big difference in the outcome.

Update: So I cut some hulls to 2.53" or so. Ran a few empties through it and lo and behold, the gun operated and they ejected OK. So I loaded some up using card wads and wax to seal the ends up for now. I hope to fire those this week. My thought is to eventually use hulls cut to the shorter length and use a roll crimper with cards for a better result. I'll report back. I'm sure many of you are in suspense....

Have you tried firing factory 2-3/4" shells in this gun? I have an unmodified short chamber M12 16ga, and it handles Win Super X field loads just fine.
