What's the minimum age to go shoot in the range?

I have been to the range, but spoke on the phone, you have to go on their website, and fill out a form for a background check, the guy on the phone said it takes about 24 hours, on the confirmation email it says 48-72 hours for approval. Took me between 30-40 hours for approval.

Can a gun range with a felony

18 but there are some restrictions you can only shoot long neck rifle.
