Smooth bore tank barrels use sabot rounds that have fins to stabilize its self, less accuracy more range and have a long life span and easier to clean, more used for anti tank.
Rifled has less range but way better accuracy using more anti personnel, it can use at rounds like HEAT but their less effective with a rotational spin on them, wears out over time.
12 g sabot slugs. Rifled slugs are for smoothbore barrels.
A smoothbore is cheaper and works just as well when using regular shot. A rifled shotgun barrel only helps if you are going to be firing slugs, but if you are it improves performance considerably, giving the slug near-rifle accuracy. If you can afford it and plan to be using slugs the rifled barrel can be well worth it and gives you much more versitility.
The 67 has a rifled bore, the 67 smoothbore does not.
probably not, historicly shotguns are smoothbore if you shoot a slug, THAT would be rifled.
Yes. Rifled slugs are intended to be fired through a smoothbore barrel. Sabot slugs are intended to be fired through rifled barrels.
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.
Yes, the barrels are rifled.
In the most general of terms, slug barrels are rifled and regular barrels are smooth bore. Both are capable of shooting slugs.
No. The barrels are not rifled

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.
