No. will handle 2 9/16 old shells or 2 3/34 modern regular pressure shells.
Are you talking 2 3/4" magnum shells, or 3" mag shells? Do not put a 3"chamber barrel on a standard receiver. Do not try to load 3" shells in a Light 12. A browning Light twelve can handle the heaviest 2 3/4" loads available. Remember to set the friction ring assembly for "Heavy Loads".
In good working condition, the Stevens 311 will handle any modern shotshell for which it is chambered. Not sure what you are asking about the .44 Magnum cartridge... sales@countrygunsmith.net
Yes, however, they may not cycle thru, and need to be loaded one at a time. Chamber will need cleaning after shooting the shorter magnum cartridge.
Yes, they are all high brass and considered magnum loads
When were 3inch magnum
No, it is/was not.
If has the magnum cylinder it will.
In a .44 Magnum revolver, yes. In a semi-automatic .44 Magnum (such as the Desert Eagle), no.
The sizes of shells it accepts will be stamped on the barrel
The Light will only accept and shoot 2 3/4" shells. The Magnum will shoot up to 3" 20ga shells.
All things being equal, there's no reason why an Ithaca Model 37 shouldn't handle saboted slugs, assuming that you aren't using 3" magnum shells in a 2-3/4" chamber. If you have any doubt, have the gun checked out by a gunsmith.
The length of the chamber in a 2 3/4 inch chambered shotgun is 2 3/4". The longer 3" shotgun shells will not fit in the chamber, being 1/4" too long. You can shoot 2 3/4" shotgun shells, of the correct gauge, in a 3" chambered shotgun.
