Yes you can but you need to make sure the choke is big enough that the slug goes through easy. I suggest sacrificing a round cut it open and slide the slug down the barrel.
Yes
Some bolt action shotguns had an adjustable choke, and it is generally NOT recommended that slugs be fired through those. If there is no adjustable choke at the muzzle, your shotgun should be fine. Stay with rifled slugs.
Pellets or slugs. shotguns usually shoot shot or pellets, but you can shoot slugs. in Indiana we use a shotgun to hunt deer and use shotgun slugs, better to use a barrel with no choke in it. cylinder bore preferred.
yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
You can, but I wouldn't advise it.
Yes. Rifled slugs are intended for smoothbore barrels (abot slugs aer for RIFLED barrels). Best accuracy with rifled slugs is USUALLY a modified choke, but can be safely fired thru any choke less than EXTRA full choke.
Can you Yes, should you NO. a full choke should not be used to shoot slugs.
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.
Yes
Not recommended for full choke
No. It is unsafe to shoot slugs in a shotgun with a full choke. A full choke shotgun may not allow the slug to pass through and could injure the gun and the shooter. Slugs will work fine in ANY shotgun that has a cylinder, improved cylinder, or modified cylinder choke. If you happen to have a shotgun with crew in chokes, it will be easy to switch chokes. Most slugs that people use are the foster- type slugs. These slugs feature a hollow base and are made of softer lead and are found at most stores. They are made by Remington, Winchester, and Federal. These slugs are more forgiving as they can sometimes squeeze through a tighter choke. Slugs like those from Brenneke and Dixie slugs are made of harden lead and are less forgiving. These slugs are safest used in shotguns that have cylinder or improved cylinder chokes.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
