I saw a Netflix movie that I can't remember the title of where the gun used to wipe out an entire house was the CJ.
Strangely, (or maybe not) the .410 is the MOST "on" pointing shotgun I've ever used.
If I snap it to the shoulder and double action a shot at anything I'm ...LOOKING...at.
It's hit!
Surprised me.
Also the amazing power of the .410 slug was truly amazing. ZIPS right through heavy gauge steel.
I don't know if its still in production, or not, sorry. But I do know its either a rifle, OR a shotgun. If it has rifling, its a rifle. Period.
It can be (and is) a .45 Colt rifle that also shoots the .410 shotshell, but its still a rifle, technically. Same thing for the handguns that shoot both. They are .45 Colts, with rifled barrels, which are also cut to allow the use of .410 shells. If they weren't rifled, they would be shotguns (smoothbore) under the law, and couldn't be sold as regular handguns.
And, yes, the power of the .410 slug is impressive, for what it is. It's a 110gr slug (approximately) and the box of 3" Winchester I have says velocity is 1800fps. That's respectable, I think.
