This is a rifled barrel converter for single shot or double barrel shotguns.

Converts 12 ga to 40 s&w.

I'm including a few extra 40s&w bullets.

never seen the likes of this, so I assume the .40 bullet just clears the rest of the shotgun barrel every time without touching bore ?

Yeah, the bullet travels pretty fast. There's a few videos on YouTube.

I wish this was 44 magnum, or 6.8 spc with 10" barrel insert.

Me too, but then if it was I wouldn't be selling it.

What's up with the bottom of that .357 cartridge? Does it have to be shaved to work in this capacity or is it just the photo?

There's no mods needed, you just put it in and shoot. The barrel does have a small notch so you can slide the empty brass out after firing.

Update: I will not ship, my area code is 91767. This barrel shoots 40 s&w only.

Price drop to $50.

So confirming the "converter" will safely shoot .357 mag?

No the converter is made for .40 only. The 357 in the pic is just an example.

Thanks for the update.
