I see nice old Stevens Favoite rifles in 25 rimfire, often going for real short money. I imagine they are less money than the same rifle in 22 because the 25 is obsolete and no longer available (at least not readily available). I like a real antique as much as the next guy, but I'd like to at least be able to use it for something.
Now, the Favorite is a take down rifle. The whole front end comes right off with no real difficulty. My question is, if I pick up an old 25, and make a 22 front end for it, will the firing pin be right for the smaller case? I know I could change or modify the firing pin, but the idea for me is that I'd like to keep the original antique together and un modified, just have a 'shooter' front end for it.
