Group thoughts on Feasibility..

Any thoughts on converting a Stevens Favorite in .25 Rimfire to 25-20 centerfire. Worth the effort for the halibut? I am led to believe that the frame and swinging block was capable of handling up to the .32 rimfire pressure. Is this a fallacy?

I do believe that's a common and simple conversion. Just keep to Black Powder loads or pressures and there should be no problems.

I believe midwayusa.com made a video on just that (or a very similar) project.

The Stevens Favorite is not a good candidate for conversion to the .25-20 or any centerfire cartridge. The Favorite is a small action with takedown which renders it unsuited for the higher pressure centerfires - the single-shot Stevens action which is suitable for the conversion is the #44, which is both larger overall and has a larger diameter threaded barrel shank. The best and strongest of the Stevens single shot actions is the #44 1/2, but those actions are fewer and more expensive. The #44 action would be suitable for the .25-20 in its standard velocity loadings, though the high-velocity loads should be avoided.

Sounds like fun but I would want to be safe. This is a 1915. Probably wind up getting rid of it and some old ammo. Although I did see some videos on .25 rimfire cases with .22 blanks...
thanks for the ideas and advice
