A bolt action shotgun in 12 gauge.
Depends on the load, angle of fire, terrain, weather, etc.. a couple of hundred yards at least.
Depending on barrel length, load and choke, anywhere from 10-100 or more yards
Depends on the BA, distance, type of buckshot, load velocity.
a 12 gauge shotgun can shoot about 30 yards accuracy
No, you can not shoot anything but 12 gauge shotgun shells through a 12 gauge shotgun. Never use any ammunition other than what the firearm was designed for.
