Well, that's just plain horrible. On another Savage collector's site they refer to badly maintained Savage 99s as "tomato stakes," but then they go on and on about how to restore them to shootable condition.
I wonder if there is a 'smith left in the US that could offset the bore on a rimfire barrel so it could be used in a switch-barrel centerfire rifle like the 219?
Thompson-Center, before it was absorbed by Smith and Wesson (really by a conglomerate who also owns S&W) used to offer a rimfire barrel for their larger break-action"Encore" centerfire rifle. I never had one of those so don't know how they accomplished it, but I suspect an off-center chamber. They don't offer it any more. Their smaller break-action rifle, the "Contender," uses a movable firing pin to accomplish the same thing. It works fine, as long as you remember to flip the switch when you change from the .22 barrel to a centerfire and vice-versa. Almost lost a nice pig that way. Fortunately (for me, not the piggie) pigs don't see or hear very well....
