Pete,

Hi!

There are several manufacturers of chamber adapters, barrel inserts, auxilliary chambers, and sub-caliber devices.

Try checking McAce at: web page

Baikal reportedly used to make such devices.

Various high-end shotgun makers, e.g., Perazzi, offer barrel liners/tubes.

Either Handloader or Rifle magazine reviewed them in 1 or 2 consecutive issues in articles by Russ Seyfried, including Handloader April/May, 2002.

Finally do a search for a thread called: "It's a guy thing" started by Chris Kavanaugh. We discussed such devices there. Alternatively do a search on my name for a post dated 3/12/02. The discussion is in that thread.

The use of chamber adapters does merit further discussion. Unfortunately I don't have any first hand experience with them. On most of my hunts I try to take at least several guns. Even when backpacking, the weight of a lightweight revolver can usually be tolerated and always rationalized (they're potentially too much fun to leave home). S&W, Ruger, and Colt have all made potential candidates for the kit gun category. I have several of the S&Ws and am quite fond of them.

Good luck,

John
