hm2,
Sorry to hear that Brazas is out of business. I was going to suggest them. The last one I bought, albeit some time ago, was $275. They used to sell a lot of them. I would imagine that any Ruger distributor could get them.

this guy has some, i have done business with him & he shipps quickly........Skeeterbsa@aol.com <Skeeterbsa@aol.com>

Ruger also used to sell barrelled actions. But there never has been a steady, commercial source for No.1 actions only.
