You can still get Autauga parts. I just contacted Autauga Rifles today & am getting some extractor springs. Autauga Arms did stop making it & they are now just concentrating on their core business, custom rifles. The company was sold about 2 years ago. Technically the guns are still warrantied but repairs are not a very high priority though. I've got 2, both 100% reliable. They recommend Gold Dots but in any case, it was designed for hollow point only. The only known problem I've heard of is a slipping trigger bar on some but is supposed to be easily fixed.
The owner of Autauga Rifle is supposed to be negotiating with an unnamed manufacturer to sell the design so it may be back in production again one day.
I got a stock of spare parts about 1.5 years ago just in case but thought I'd add some extractor springs to my stock.
