If the question relates to shooting regular shot pellets out of a shotgun which is fitted with a rifled barrel for purposes of home defense, then the answer would be "it will work fine". A home defense situation MUST entail engagement at close range since a home invader who is a significant distance away is not a threat and thus is not a valid target. When shooting a shotgun at close range, having the pattern spread quickly would improve the probability of a hit. A rifled barrel would impart a spin on the shot cup and thus to the shot column, causing the column to spread immediately after leaving the muzzle.
If the question is about something else, you will have to improve the wording.
Not safely
Yes. Rifled slugs are intended to be fired through a smoothbore barrel. Sabot slugs are intended to be fired through rifled barrels.
yes.
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.
yes a rifled shotgun barrel or smooth shotgun barrel
In general, rifled slugs are intended to go through a smooth bore. The twist rates of a rifled slug against a rifled barrel may not agree. If you were trying to get the best out of your rifled barrel I would think that going to a saboted slug would give better performance.
Yes
You can, but, it will not be a good thing.
That is correct.
Neither barrel is rifled.
You look down the barrel and if it is swirled it is a rifled barrel and if it is not swirled it is a smooth bore
Rifled Slugs are meant for smooth bore barrels mainly. The rifled slug is made of lead and so if you shoot it through a rifled barrel the lead touching the rifling will cause some of the lead to peal off and can build up over a very short period of time. Also the facft that you are shooting a rifled slug through a rifled barrel would cause the bullet to become extremely unstable and inaccurate. Rifle barrel sare meant for sabot slugs (slugs with a plastic wad surrounding the outside). You should eb good though to shoot a rifled slug out of your barrel with a mod choke tube, but smooth bore deer barrels are ideal.M.I.
