The 12 g Marlin 200 single shot shotgun SHOULD be marked on the barrel, something like "model 200 12 g 3" Modified" That means it will fire the 3 inch magnum shotshell, and has a modified choke. If you have a shotgun marked 2 3/4, do NOT fire a 3 inch magnum, even if it will chamber. The forcing cone will not have enough length for the shell to open, and it will cause unsafe high pressures. Every 200 I have seen (a limited number) WAS chambered for 3 inch Magnum shells.

Misidentified. Exactly how is the gun marked? sales@countrygunsmith.net
Marlin made a lever action .410 gauge shotgun from 1929-1932.These were made as a stockholders promotional firearm.The New model .410 was made from 2004-2005.
No. But there are revolvers made to shoot .410 shells that also fire .45 Colt cartridges,
None. While there are firearms made to shoot .45 Colt AND .410 shotshells, they are designed and made to do that. A regular .410 shotgun is NOT made to do that safely.
