An indoor range near one of my California friends has some simple rules:

1. Store ammunition in rental guns.
2. Handloads okay in customer's guns.
3. Lead bullets, copper-plated bullets, copper jacketed bullets are okay. No steel jacketed bullets. They told me that steel jacketed bullets cause damage to the backstops.
4. Black powder muzzleloading rifles and handguns are okay.
5. No centerfire rifles.

I haven't been there in about a year. I hope the rules haven't changed. However, there is a nice outdoor range just East of Carson City on Hwy 50, and an nice outdoor range South of Gardnerville off of Hwy 395.
