They have 3 veterans range officers for this range. If they are working, they will let you fire. If they are not there, you can not. Do not go to front desk and ask. They will say no. Go directly to the range officer and ask.
Depends on the range guys. Some allow it some dont. Best to call.
If I remember from the safety video correctly, .50 BMG is specifically called out as not being allowed but it would probably be best to call and verify.
