Antelope Sniper's suggestion is a very good one.
However, every range I've shot on or had inner-workings with, required a stamp of approval. When dealing with a range such as this one, it would appear that is not the case.
If somebody is going to claim something is dangerous they should focus on proving that. Audio of ricochet and stray rounds should be pretty easy to get if you wanted to go through the trouble. Or finding projectiles near the house or on neighboring property.
That's why we call you the expert.
