The Winchester Model 12 was one of the best pump shotguns ever invented, but I'm afraid trying to chamber a round 1/4 inch longer than the gun was designed to fire would be very difficult and the pressures generated would be higher than the 9/16 was designed to handle.
No, it is/was not.
Is it chambered for magnum shells? If not, the answer is NO.
As the number 3 indicates,your Winchester model 42 can chamber either 2 1/2in,or 3 inch 410 shotgun shells.
Yes, However, the reverse is not true- 3 inch shells may NOT be safely fired in a gun chambered for 2 3/4 inch shells.
Yes, However, the reverse is not true- 3 inch shells may NOT be safely fired in a gun chambered for 2 3/4 inch shells.
I'm not 100% positive. I do know it has to be chambered for such. My M-12 shoots 2-3/4.
Yes, you can.
With the serial number that you have provided,your Winchester model 1912 pump action shotgun was made in the year 1916.You should be aware that all Winchester model 12 shotguns chambered in 20 gauge from 1912-1927 were chambered in the 2 1/2 inch length,not the present day chambering for 2 3/4in shells.
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.
YES IF ITS MARKED 3 INCH, THEY NEVER MADE BLACK POWDER SHELLS IN 3 INCH FOR 12 GA GUNS.
The spec's on what the gun is chambered for will be stamped into the barrel right under the name and model number. If it says 2 1/2" don't try shooting 3" shells in it, it may blow up in your face.
All day long. Any shotgun can handle shorter shells than it is chambered for as long as they are the same gauge.
