Things to keep in mind about ammo use. If you punch a hole in a steel trap with your ammo, the range owner is now out several thousand dollars to replace that panel. Are you going to pay for it? You will at our range. We will have an approved list of ammo that can be used on our range, and it is very extensive and growing. In a nut shell, no AP, API, Tracer, or APIT. FMJ and any blended ammo (except the LeMas stuff, and not because I worry about it punching thru the trap, I just dont like their ammo) are all good to go.
We will check your ammo to make sure there is nothing funny being shot there, and it must be in the original box (yes the ammo can surplus is shipped in is the original box) and we will walk the range with the customer at the begining and end of every hour to make sure you do not shoot on a damaged lane and that you did not damage the lane while you were shooting. That may take 10 minutes off the range time, but gives you and the facility piece of mind that everything is safe and fully functional.
On ventalation, it is VERY, VERY expensive. Our system for the ranges alone is costing us over $700,000. Granted it exceeds all OSHA, NIOSH and Dept of the Navy exposure limits by far, and it will leave the facility smelling like a regular building and not a range facility. But that is the first place people cut corners and it is the first place that will cost them big money in the long run.
