slide a 3" shell in the chamber manually and see if it fits without being forced.
Around $350-$400, a little more if it is the single-trigger version.
The only length I've seen is 2 3/4 in shells. That is the length of the chamber on my Model 77-B in 16 gauge. Early guns, those made prior to the 1930s may have 2 1/2 inch or 2 5/8 inch chambers, So, while modern 16 gauge shells are 2 3/4", early 16 gauge shells were 2 1/2".
yes
1926 IS THE YEAR THAT WINCHESTER WENT TO STANDARDIZED 2-3/4" LENGTHS ON THEIR 16 AND 20 GAUGE SHELLS.
FYI- It's .22 caliber, as in .22 of and inch, gauge is for measuring shotguns or wire
Anything up to 3"
DO NOT ATTEMPT TO USE 3 INCH SHELLS IN A FIREARM NOT MARKED FOR THEM!!!!!!!!! Yes there are manuals for the firearm.
About $400.
Yes it does I have one.
If your shotgun is a 12 gauge pump, then you have a High Standard Model 200 (Flite King). The standard 12 gauge shell is a 2 3/4 inch shotgun shell. It can be anything from #8 birdshot to a deer slug.
A Marlin lever action rifle that was made in 1937 will be a Marlin model 36,1st Variation.These were produced from 1937-1940.
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.
