yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
You will need to change barrel's, a accu choke is not on a slug barrel.
You need to contact Remington for a correct answer.
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
n You will need to contact Mossberg to find out for sure.
You will need a replacemetn barrel that is rated for steel shot.
First, check your owner's manual. Some makers may recommend that slugs NOT be fired (usually with makers of variable choke guns) In theory, you can use any choke as open as full (Extra full used by turkey hunters, not good with chokes). In practice, MOST shotguns will shoot slugs most accurately with a Modified choke, but you will need to test fire YOUR gun, and see what it likes.
It is possible to fire a shotgun without a choke, but it is highly not reccomended, and they don't cost that much If you select a barrel with no choke (cylinder) it will cause the pattern to be looser than for a barrel of a shotgun that has a tighter choke. The extreme is "full choke" which keeps a tight pattern out to the effective range. Full choke is typically used for waterfowl. A shotgun that is pressed into double duty (shot for small game and slugs for big game) would work well to have modified choke. Slugs have to be designed to fire through a full choke without blowing the barrel but you will certainly shorten the life of the barrel by firing slugs through a choked barrel. If you can afford an extra barrel, then use a cylinder (no choke) for slugs. Remington and other shotgun manufacturers have interchangeable choke tubes (see link) that allow you to screw in the appropriate choke for your quarry.
You need to have it examined by a gunsmith. The answer could be yes, or it could be no. Depends on how it is choked.
