When you remove the smoothbore barrel and attach a rifled slug barrel to your shotgun, isn't then technically a rifle?
And how does that affect what you can carry during specific seasons?

In NY state (at least), rifled shotguns are legal in shotgun-only areas.

In Michigan a rifled shotgun is still a shotgun.
It has to do with the shell itself, not the firearm.

I would guess that it would be called a shotgun with a rifled bore.

If I put a smooth-bore barrel on my .308, besides not shooting for crap, I am pretty sure it would still be called a rifle or maybe a paperweight. It certainly would not be a shotgun. ;)

It still a shotgun with a rifle slug barrel.

If you have a rifle with a diameter of over 0.5 inch it is considered a destructive device under ATF reg. from what I remember and needs special paper work to own.

On hunting reg. I am not sure(vary from state to state) some areas require slug guns for hunting because of their reduce range/penatration (safety issues).

to my understanding: if you start with a finished shotgun, you can modify it so it will be reclassified as a short barrel shotgun, an aow, a dd, or a paperweight - but not a rifle. if the reciever was manufactured into a finished shotgun as a shotgun, then that's what it is, as far as the atf is concerned. there's more to a shotgun than having a smooth bore.

Actually, any firearm with a bore of >.5" is a DD, whether it has rifling or not. Most shotguns are not DDs, because the ATF says they have a "sporting purpose". The USAS-12 and Streetsweeper used to be ordinary shotguns, until the ATF decided that they had no sporting purpose and poof, all of a sudden they're evil DDs.
