No, not yet
yes a rifled shotgun barrel or smooth shotgun barrel
probably not, historicly shotguns are smoothbore if you shoot a slug, THAT would be rifled.
That is correct.
Firing lead shot through a slug barrel will not damage the barrel. The rifling will distort the shot pattern and you will get less than desireable results.
i have a 12 gauge unrifled barrel 500 model.what type of slug do you reccomend for the mossberg
A rifled slug- yes.
You should check with the barrels manufacturer about it's ratings, but I've never seen a slug barrel that wouldn't handle lead slugs.If you're talking about using shot shells...Since shot is contained in a wad, it never actually touches the walls of the barrel as it travels down it. The shot won't damage the riffling in the barrel, but since a slug barrel doesn't have the same choke as a shot barrel, and the wad in a shot shell isn't designed to spin, the shot pattern is going to be messed up.It's not a good idea.
Slug barrel
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.
The amount of constriction at the muzzle
HR Ultra slug for sure.
11 - 48 slug barrel
