Are you wanting to keep it rimfire?  If you choose centerfire, I've heard of using 22 hornet cases with the bases reduced, and shortened.  If you want to keep it rimfire, there is a technique using Hornet cases with the bottom bored off center to allow the use of nailgun cartridges to get the fire started. 

Last time I checked, the folks at the SSE still had back copies of the June 2010 issue available. See "Feeding the .25 Stevens Rimfire" for the details. Essentially, make a .25 Stevens shell to hold a .22 RF case to use as a primer. Light loads and 65 gr. cast bullets without the gas check work quite well. I believe that I started with a .22 Hornet case, but I'd have to look at the article again to check what I wrote. As we get older, we get better at forgetting.

I've seen these rimfire resurections talked about here and other places as well. Something nobody has mentioned, that I've seen, is whether these leak gas from the hole where the .22 "primer" is located? It seems that unless it's so dang tight that the rimfire's primer would go off or the case crush, that the fit would assume the nature of a worn primer pocket in a normal case. Would someone please explain what I must be missing on these conversions?  Pat

I've tried them for .44 rf, .38 rf, and .32 rf. and not had any leakage with any of them. The rim of the .22 blank fits into a recess cut into the turned cases on the ones I got, so when chambered, and the breech closed, it creates a good seal. I'm uncertain how one in .25 works, as I haven't seen an adapter for that caliber.
The issue that made me give up on all the others was removing the blank from the adapter case after firing. They open up, and expand inside the adapter, and it requires punching them out, which can sometimes be a chore. Then push in a new blank, pour a charge, and seat a new projectile. Just wasn't much fun for me, and I tossed them in a drawer.

No need to make them, as Dixie Gun Works sells them. I believe they sold them in sets of three, along with a can of blanks, and a couple tools to punch them out. Used be around $5., but looks like they're $6.50 now, and I don't see any blanks with them.

I have also used the .27 caliber nail gun loads. Worked fine for plinking. I need to take some more time and try them is different rifles. I have a few with good bores including a really nice 418 Stevens. I picked up a good supply of .27 nail gun loads at the local flea market a while back
