Yeah, it works fine with the little rimfires it was made for, but for anything warmer, it's a little rickety.

When you guys say you rechamber and convert these .32 RF guns for ".32 S&W" do you mean the original shorter round or the .32 S&W Long?

I could see the Long in a Marlin, but some of the European "Olympic" (autoloader) loads for it are fairly warm, maybe a little too hot for a Favorite? Even the commonly available Fiocchi wadcutters are hotter than normal US loads.
