Because of the possibility of blowing up the barrels, it is not recommended for safety reasons.
No
Not recommended.
Yes. The Marlin model 556 is a bolt action shotgun. It has a detachable magazine which holds two rounds and one round in the pipe for a total of three rounds. It is able to shoot 3 inch ammunition.
it means you can use 22 short rounds 22 long rounds and the modern 22 long rifle rounds and it will shoot them all
yeah, i shoot my 1923 model 12 ga. all the time, buy the AA rounds at walmart, they are lower presure than normal, and they are cheaper. just make sure they are 2 3/4 LEAD shot.

Put on in the chamber and then top off the magazine.
You should be OK with standard loads.
No you cannot, the steel and manufacturing techniques in the late 1890's cannot handle the pressures of modern 'smokeless' rounds of today. The marlin 1889 and other firearms of that period fire blackpowder cartridges. And a number of ammo companies today sell blackpowder rounds for the Marlin 1889 and other firearms. You can go to midwayusa.com and other internet ammo sites to get it. However...before you fire any antique, get it checked over by a good gunsmith to make sure it is mechanically and otherwise safe to shoot.
A shotgun can shoot up to 80 yards it it depends on what the choke is on the gun.
a 12 gauge shotgun can shoot about 30 yards accuracy
If your shotgun has Damascus barrels,then by all means do not fire modern smokeless ammo through your shotgun.I would have your shotgun looked at by a qualified gunsmith before attempting to fire any ammo through a shotgun of this age.
