Good day everyone. After many negotiating sessions and too many beers to count I have finally acquired on a trade with one of my friends this nice little take down rolling block chambered in 25-10 rimfire. I really don’t know why I like it so much but for some reason I just had to have it. Considering how hard it is to find and expensive the ammo is, I am thinking some sort of caliber conversion. I hope to hear from some of you talented CGNers who have done a conversion on one of these things about what I am getting myself into. My first thought is .22lr as ammo is cheap but I already have a number of .22lr rifles. My next thought is a 22 hornet. Would this mini rolling block action be able to handle a small centerfire cartridge like this? If so what would a guy expect to pay to have a smith do a conversion on one of these including a new barrel? If anyone out there has any other ideas what I should do with this little feller please chime in as the plan for this project is very much still in its early stages. Anyway here are some pics.

Your best bet is to reline it to 22lr and enjoy it for what it is.These little guns were not designed for modern centerfire cartridges especially the takedown versions
 
I would also like to know what the value of this rifle might be? I think my buddy might have took advantage of my inebriated state on the trade lol.
 
You could experiment with, or research the idea of shooting .250 round balls in front of a 25cal Hilti type cartridge. Some of the people on CGN use that method for shooting the old 25 rf guns at a reasonable price. Personaly, I don't see the merit in changing the calibre to something else. You would never get your money back out of the rifle if you decided to sell it at a later date.
 
The #4 rolling block is pretty weak and suitable only for rimfire calibers and that does not include 22 magnum. There is very little metal ahead of the pivot through the breach block. Definitely not suitable for centerfire shells and definitely not for 22 hornet. You should check the diameter of hilti shells in your area. Unless I am mistaken they are 27 caliber although I think they are also made in 22 caliber. You can install a 22 barrel on the gun with no modification to the rest of the gun. You might be able to make up some shells that accept a 22 blank and allow you to shoot 25 cal round ball out of the gun. I think #1 buck is the right diameter but you would have to check specifications on the various buckshots

I tried to buy one of those once, like you they just strike me, My plan was to keep it 25-10 I don't recall exactly what I planned to shoot but it involved buck shot. If the bore is good on that rifle IMHO you would be remiss to alter it to 22 lr. 22 hornet is for sure a no-no.
 
Very nice pictures.

I have one in .32RF that is quite loose and the barrel is completely rusted out so found a .22 liner that I hope to use. The only centerfire that I might consider on one of these would be something like a .32 Colt short and then probably just with black powder or gallery loads.
 
Thanks for the info guys. With what I learned here I am thinking I should get it sleaved to 22lr. If it were in better condition I would just leave it as it is but the bore is a little rough and the stock looks like it has been sanded down. Do anyone of you guys know of a good gunsmith that can re line the barrel on one of these?
 
I had a similar conundrum with an old Stevens Favourite takedown in .32 rf. I had read about lunatics rebarreling them to centrefire rounds (.32 Short, .32 Long, .22 Hornet!), but in the end I decided to save face (literally!) and had my gunsmith fit an old 26-inch cooey .22 lr barrel which I ground to an octagon and polished up. I still have the original barrel, breechblock, and extractor, so I can change the rifle back in a couple minutes if I find any more .32 rf to use. I think sleeving to .22 lr or fitting a new barrel will be your best bet. It's sure a nice rifle you have there!
 
the Stevens model 44 was chambered briefly in 32-40. It was discontinued because of excessive stretching and wear and tear. This was partly a result of the introduction of a high velocity version of the 32-40. The model 44 is a large size version of the favourite. I did see a favourite that a gunsmith friend changed to a true falling block by filing or milling shoulders inside the frame to support the breach instead of the toggle link. Having said that, the wall thickness of most favourites is pretty thin for that sort of design
