Check out Thompson Center. They make the Contender and Encore. Frame is basic, but you choose the caliber (.22LR to .45-70 or 20 ga.). Contender can do rimfire also. Encore is centerfire only. They are available in rifle or pistol versions. And you can get black powder versions as well. Meets most of your requirements except for autoloading/bolt action. They are single shot only.

Biggest problem: it can be a bit pricey.

Be careful of the laws though. Short barrel (less then 16", 18" shotgun) on rifle stocked or registered frame is Federal Felony. California laws are different, so exercise more caution there.
