Possibly, a copper slug is made for a barrel that has riflings in it and has a straight bore, so if you try to shoot it out of a smooth bore you could mess up the choke, because the copper is solid where as a rifled slug is made of lead which is softer and is hollow in the back side with a plastic piece as a filler to allow for compression. Also if you did shoot a copper slug though a smooth bore it would not be accurate at all.
In short, it is a barrel designed to fire slugs. Some are smooth bore which are intended to shoot rifled slugs or buckshot, while others are rifled and intended for shooting sabot slugs only. This is a very good and trusted answer. lcj
In the most general of terms, slug barrels are rifled and regular barrels are smooth bore. Both are capable of shooting slugs.
You can, but manufacturers typically recommend that you do not. Shooting lead pellets will be less damaging and would require alot of shooting to cause any serious damage. Shooting steel or tungsten, however, will cause significant damage in a short amount of time. A smooth barrel will handle pellets, buckshot, sabotted slugs or standard slugs. A rifled barrel should be used for sabots and slugs only.
Of coarse that's what slugs do :)
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
any kind will kill a deer but if you have a smooth barrel than u need smooth slugs if you have a rifled barrel you need a rifled slug
Yes
It says not to use slugs so you probably shouldn't. Follow the engraving.
Depends on how old the shotgun is.
Rifled slugs are made of soft lead purposely for use in smooth bore shotguns. Actually the "rifling" on the slug deforms to allow the slug to pass through the choke in the bore. If your firearm is of modern manufacture and in good condition it should be safe. Of course it goes without saying that you must use the appropriate type (i.e 2-3/4", 3", etc.) and gauge (410, 20, 12 etc.) of ammunition for which your firearn was designed. If in doubt, have a reputable gunsmith check it out for you.
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.
