I rank it right up there (or down there) with the Judge. Interesting oddity, but doesn't really fill a hole in my collection.
One question though, why did he pull back and release the charge handle, and then hit the bolt release? I am guessing that was an editing error, or to show that the bolt locks back after the last round was fired. I don't know, it just caught my attention.
Brings more than a few thoughts to my mind
The positive, If a bunch of "wanta kill all the zombie" folks buy these and take them to the range, well 410 shells may become less expensive (increase in demand/faster sales/bigger production runs = (hopefully) lower costs.
The negative, Well it obviously is a very expensive shotgun, with mag capacity beyond what you can take to the field and hunt with.
Mr Smith, why did you put multiple rounds of buckshot from your large capacity mag assault shotgun into the poor, misguided convicted rapist, who had broken into your home, only to die in a hail of deadly lead? (though I also rate that as a positive, 1 less person who makes bad choices = less chance for it to breed more)
With the shotgun range, and the 410 shot, what advantage does it provide over a .410 pump or a .223 or a/k?
