We use a private range near Pala and Temecula as well as Corona. Corona is good for load development and any distance Private range is the way to go. ELR we go to Barstow
Corona range is not as bad as I anticipated. 100yd rifle range is never packed even on the weekends. Seems most of the people go to shoot handguns or shotguns.
I'm in Corona hit me up if you plan to head that way.
