Sorry guys, I haven't been on here in a few days. I actually contacted Winchester Ammo about selling cases, and they never so much as e-mailed me back, so I guess that answered that.. I agree that this would be perfect for somebody like Buffalo Arms. Perhaps somebody with some clout on here should contact them? Yes, I did shoot them, and they loaded and shot fine, though they chamber a touch on the tight side, owing to the thicker rim. It worked fine in my gun. As for pulling the bullets, I just used a pair of pliers. The bullets are tiny- they pull out after a couple twists.

Yes, it will take someone with pre-existing credibility as an ammo manufacturer to get them to pay any attention. Pick one, then let's team up and start lobbying. Gotta convince 'em that there is a market.  Lie a little if you have to.   Roll Eyes

The thicker rim will be just the ticket for old rifles having a bit too much headspace.

Any thoughts about reloading these cases in the same manner as has been done with normal 22 rimfire?

Once you had a supply of converted 25 rimfire cases, I don't know why you wouldn't, but not sure it would be practical either.

On second thought, why not just pick up spent range brass,  reprime it as in the video above and load it in the same manner as the original poster did his?  I have an old Stevens 44 in 25 rimfire that I've been agonizing over what to do with, and might have to give this a try.

There's no reason you couldn't do that. The .17 WSM cases are made so heavy duty on the rim, they barely indent from the firing pin (gun isn't wore out, it knocks the heck out of original ammo and .27 cal nailgun blanks). When we shot them, we even commented on how you could probably reload them if you were inclined to do so.

I only have one .25RF and have been contemplating selling it just because I only have a few boxes of ammo, and rarely shoot it. I wish someone would indeed make .25 Stevens RF ass it might make me change my mind!

Yes a Stevens scope, and a Stevens bore! The Ballard barrel is marked "rebored by J Stevens .25RF" marked under the forearm wood.

@willsweptline :

How did you expand the mouth of the case?  I'm making an expander plug for a Lyman M die now.  But I need a shell holder for the press.  Looks like a .32 ACP holder might do it.  Had to order one.....we'll see.   Did you have another way?

Breach Seat .25 Stevens ?

So, I have a 1915 Stevens Favorite and been reading about different options re: ammunition. I read somewhere about someone using .25 cal airgun pellets just dropped in the chamber, then a 27 cal. ramset blank in the chamber behind it.
Might work ? Or inviting disaster ?
I confess, I bought a box of .27 Ramset blanks and popped off 3 of them -- nothing bad yet. (other than the rim on 2 of them dropping behind the extractor).
No airgun pellets yet.  Roll Eyes

I've seen that, too.   Have not had a .25 Stevens good enough to try it.  Supposedly some of this powder-tool blanks are pretty energetic.

Yes, on the box of blanks that I bought, there's a "power chart" that indicates power levels of 1 through 5. Level #4 is the only one I've seen around here. The 4's were rather loud -- that's what gave me some "pause". Or would it be more like "sober second thought"?  Undecided

I'm going to repeat this here, hoping for some replies.

I've always believed that the .25 RF Stevens used a .251 bullet. Barnes says .251.   Other experimenters who have posted their projects here and elsewhere are using .251 bullets.   

Now the kicker.  One member here has made a centerfire version using Hornet brass, and HE is using .257 bullets.  Night before last I dragged out my tatty Model 12 Marksman, and found that IT is bored and rifled for .257.  A .251 bullet will drop right through it.  The bore isn't all that bad - rather dark and rough, but with plenty of rifling still showing. 

There are other testaments on both sides.  Would be interested to get more feedback.  And if anyone has an original .25 RF cartridge, what are the actual measurements?

I have a couple dozen of these. There isn't much of the bullet sticking out past the mouth of the case that is easy to measure. The bullet steps down almost immediately.

I measured a few of them and they run .251 - .252.

Thanks Jerry!  

That settles it for the "case" of genuine period ammunition.  The O.D. of the case just below the mouth would be .272 or so? 

Which leaves the mystery of why I (and apparently others) have barrels that are much too big for that bullet, and chambers equally oversize, yet are still marked .25 Stevens.  

I still picture some evil gnome in turn of the century Chicopee, grinning to himself and muttering "There, that'll confound 'em".

A random sample of loaded rounds measured at various points around the neck average out to about .277. The bullets are quite oxidized so maybe they have swelled the cases that much. A long time ago I had a Favorite in .25 Rimfire. These cartridges would chamber but the couple I dropped the hammer on failed to fire. I don't remember if they chambered hard or just slipped right in. I hope this is of some help and doesn't add to the confusion.
