Not safely
Yes. Rifled slugs are intended to be fired through a smoothbore barrel. Sabot slugs are intended to be fired through rifled barrels.
A rifled slug can be fired from a smoothbore barrel with relative accuracy to about 100 yards. By relative accuracy, I mean that shots can be held in a 5 inch circle. That is about the size of the target zone on a deer. For a rifled barrel, rifled slugs should NOT be used, but sabot slugs can be.
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.
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.
There are grooves in a rifle barrel, or external screw-helices on so-called Rifled slugs, which are fired from shotguns, but are externally rifled for spin stabilization?
12 g sabot slugs. Rifled slugs are for smoothbore barrels.
Rifled slugs were designed for smooth bore barrels because they lack rifling. Sabot slugs are made for rifled bores but they can fire through smooth bores with loss of accuracy. I am not sure about rifled slugs in a rifled barrel because I think the bullets rifling can improperly connect with the bores rifling and you risk scratching the barrel.
Yes. That's the only type of shotgun you should fire a sabot slug from. Rifled shotguns are intended for rifled slugs only. Actually, the opposite is true. Rifled slugs are preferred for smooth barreled shotguns. The 'rifling' on the slug is actually just fins that permit the slug to squeeze through the choke on the shotgun barrel. Sabot slugs are intended for rifled barrels, as they will give better accuracy. Some sabots may be used in smooth barrels, but you are paying more for sabots and not getting the accuracy you would get by using a sabot in a rifled barrel.
Slugs! If its rifled it is a deer hunting barrel.
Depends on what the barrel is choked.
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.
