The one that gives the best accuracy. You will have to fire as many different types as you can afford to find out.
Yes
Yes. Rifled slugs are intended to be fired through a smoothbore barrel. Sabot slugs are intended to be fired through rifled barrels.
That is correct.
a slug is normally use in a shot gun and they are not rifled a gun with a rifled barrel should shoot a Shell that is the same caliber as the gun.
Assuming you mean a barrel that is for lead pellets, if the barrel is not rifled, steel shot will not damage the smooth barrel. If it is rifled however, steel shot will in fact damage the rifling.
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.
Slugs! If its rifled it is a deer hunting barrel.
no slugs should on be shot thru a improved cylinder shotgun. if you shoot thru any other choke it can cause the barrel to split
Depends on what the barrel is choked.
Yes you can. Lead Shot is Lead Shot. I shoot all kinds of different sizes of shot out of my Mossberg and Remington Shotguns. What you do not want to do is shot a slug out of barrel made for shot. Get a rifled barrel for that.
I have no personal experience with this. What follows is information from a reputable local gun dealer. Rifled barrels are designed primarily for use with sabot slugs. Buckshot will not harm a rifled barrel because in the barrel, the plastic wadding holding the shot together will be the only portion of the projectile(s) in contact with the barrel. Firing rifled lead slugs will lead to difficult (nearly impossible) to clean out accumulations of lead in the barrel & negate the rifling because the rifling of the slug & the rifling of the barrel will not match up.
Yes, but, the results will be dismal at best.
