500 yards near Chandler/Mesa-AZ?????

I am getting ready for a Wyoming mule deer hunt I was wondering if anyone knows where I can go shoot up to 500 yards in the desert near Chandler or Mesa AZ. I know that Rio Salado & Ben Avery have long ranges but you have to be a member & enter tournaments before you can shoot on those long ranges so 300 yards is the max I can shoot at either place.

Please let me know if you know anywhere. Thank you!!!
