Simunition
Thanks!
From the description, it sounds pricey, but I found 50-round boxes at $0.90/round in 9mm. I'd suspect that in a bulk buy for a training facility they could get it for half to two-thirds as much.
All of that would mean that one would not have to arrange for a lot of land in a remote location forcing customers drive forever. It would make an urban setting into an affordable business, as the buildings would already be there. Nor would it be necessary to clear the area in some cases... Why, I'd suspect one could pick up an appropriate location in Detroit for next to nothing! Additional urban ferals with which to enhance the sense of realism would be free! Not to mention the occasional call to prayer floating across the landscape, all for effect...
Of course, one might have to fight their way in to get to the facility. ;-)
I’ve seen some of that used. Pretty cool stuff
