I was looking into this range, thought maybe someone here has been there. They say they're the biggest range in the state. Seems like they've got impressive [on paper] facilities (as far as NJ is concerned). So, anyone been?

I have not been to their range. I understand that they have nice facilities.  Their rifle team dropped out of the tri-county league high power matches because of attrition.  Hutton Hill Rifle & Revolver club is not far from there depending on where you live. It is in Winslow township near Hammonton.  Send me an e-mail if you would like to try the range as a guest. Besides that we need you on our team!
