As a general rule, no.
Either. In general, slugs can be fired through any standard shotgun barrel. An exception is for Extra Full Chokes, which are not standard. Best accuracy with slugs in probably modified choke.
Yes. Slug barrels have a different "Choke" then shot barrels that make them more accurate when firing slugs, but you can fire slugs with a stock 1200 barrel.
yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
Yes. Rifled slugs are intended to be fired through a smoothbore barrel. Sabot slugs are intended to be fired through rifled barrels.
Of coarse that's what slugs do :)
Slug barrel
The Remington Mohawk 48 is a semi-automatic shotgun, and while it is primarily designed for bird and small game hunting, there is no specific slug barrel made for this model. However, you can use rifled slugs in the standard barrel, provided it has a smooth bore. For optimal accuracy with slugs, many shooters prefer to use a shotgun with a dedicated slug barrel or a fully rifled barrel. Always check your local regulations and manufacturer's guidelines when using slugs in a shotgun.
no
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.
The mossberg Model 88 maverick can definitely shoot slugs and with fair accuracy too with the un-rifled stock barrel. Try the Winchester Super X 2 1/2 inch 1 oz. But hang on to it or it will hurt you. The recoil is roughly doubled.
No.
They don't ! Slugs are exclusively vegetarian and have no interest in harming people !
