Not any that don't cost an arm and a leg. The only one I know (relatively close) is out near the border (near Delzura), about 1.5 hrs from Mira Mar. South Bay Rod & Gun club. It only goes to 300yds though. Other than that it is the desert or nothing (about 2hrs each way), and with temps right now, it'll be a few months until it is anywhere near bearable.
Camp Pendleton does have the Santa Margarita Gun Club (if you're military, retiree etc.). Goes out to 600yds (Wilcox Range).
