There are several very big problems with Ben Avery and it's proximity to the greater Phoenix metro area.
1. The SDZ of any range where center-fire rifles are used is huge, often 3 miles or more. The only alternative to this is requiring shooters to fire the rifle through a culvert tube making it nearly impossible to put one over the backstop. There is no practical way to do this on many of the ranges at Ben Avery, specifically the Metallic Silhouette range.
2. Ben Avery occupies a huge piece of land that is closed off to both the public, and the individual clubs a huge portion of the time. I remember when it was Black Canyon and it wasn't fenced in and the gates locked 24/7. Now you can drive past empty ranges that stay empty for weeks on end on your way to the public 100yd zero range or the shotgun trap/skeet facility.
When the State of Arizona decided to conduct a hostile takeover of a number of range facilities, I said openly that it was a bad idea. Probably 80% of these facilities is off limits to the Public 100%, of the time. Only the Clubs can use many of the ranges, and the MOU restricts them to one day per month, or at least it used to.
They tried to do exactly the same thing in Yuma at the Adair Ranges.
When States take over Range facilities, people simply find a place out in the desert against a hillside to shoot. Old lawnmowers, tv sets, washing machines and even old cars accumulate because folks don't want to deal with the State ranges.
The fact is, Ben Avery is going to be surrounded by urban sprawl eventually, and be forced to close. The way ranges used be operated by local Clubs was much better in my opinion.
