Yes, a 20 gauge shotgun can shoot slugs accurately from a smoothbore barrel, although the accuracy may not be as high as when using a rifled barrel. Smoothbore barrels are designed primarily for shot, but many smoothbore shotguns can still effectively fire slugs at moderate distances. The key to achieving better accuracy is ensuring the slug is properly sized for the shotgun and using a suitable sighting system. For optimal performance, it's often recommended to use a rifled slug designed for smoothbore shotguns.
Depends on the ammunition. Rifled 12 gauge slugs are accurate to about 150 yards
what do you normally shoot out of it
Definately not. I can't think of any offhand that can, but if it is not marked on the barrel then it cannot shoot them.
Shooting rifled slugs is the ONLY way to shoot thru a smoothbore for deer. If you shoot sabot slugs thru a smoothbore, it will not spin and therefore not be accurate. For accuracy, the slug must spin out of the barrel. Either shoot a rifled slug thru a smooth barrel, or shoot a saboted slug thru a rifled barrel.
Depends on what the barrel is choked.
Have a gunsmith check the gun before you fire it.
More accurate than 90 percent of the people who will shoot it.
Most shot guns can handle deer slugs.
Lacking a slug barrel, improved cylinder works best for slugs.
It starts to drop the instant it leaves the barrel
It's supposed to shoot 10.7 m but it's more accurate when you take the barrel off. (yes, it comes off)
Wall hanger. Do not attempt to shoot
