So pretty much everything you asked has been answered.
In short - this is a piece of flat land, with a flat dirt berm. It is not a tac range, does not have a lot of typical public range stuff. The biggest benefit of this range is that we are allowed to shoot rapid fire, NFA, and a little tannerite. It is NOTHING like the TV tac pits.
Moving and shooting is not possible, unless you were the only one that and set up your target stands very carefully.
The furthest typical shooting position/firing line is just over 100yds. In the past, we have set up there.
For this shoot.... I would like to throw out an idea - we set up on the 50 yd line. Most people are shooting offhand... rifles and pistols. Shooting full auto from the 100yd line is very difficult to keep every round in the berm.... ground strikes will send it over the berm. There is no real happy medium. Target shooters will want to set up at the 100. NFA, bump-firing, and pistol really should be done under 25. Either that, or we could set up on the 100, and then just move to the 25 for NFA/bump. I dunno.
As far as steel goes - yes, this place would be great for setting up some small steels. Provided we were no closer than 100yds.... shooting steels with high velocity rifles under 100yds becomes a bit dangerous. If we moved to the 50, thats a bit close, and our steel would get damaged by the .223 rounds. We could set up steels for pistol only.... but someone always will shoot it with a rifle, not knowing any better.
Your call.
