	Does any body still manufacture 25 rim fire ammo? Thanks for your answer, Hank

	There are some alternatives that have been discussed at length here if you do a search.

	The easiest way to substitute for 25 RF ammunition is: * Buy 22 Hornet cases * Resize them to 25 Hornet * Trim Hornet cases to 1.125 * Load with either a low charge of Unique or with 10grs black powder

	A neighbor has about 45 .25 shorts (CIL) he would sell for $50 plus the UPS. From estate of one of his friends. They looked in decent condition.

	John Boy, Will there be enough primer area for the firing pin to make a good hit ,or would there have to be work done to the action? ron

	John Boy. Would there be enough primer area for the firing pin to make a good hit, or would the action need to be worked on? ron

	Answer is no. The .25 RF firing pin is too far off center. What rifle? Some are ridiculously easy to rework to hit a centerfire primer, others not. (Notably the Stevens 44 and Favorites) There's a bunch of guys using powder-actuated tool cartridges with breech-seated bullets, others are machining the shortened .25 Hornet cases to take a .22 blank as the primer. A .25RF firing pin will almost always give a concentrically located .22 RF rim a good hit.

And if so, do you ream it to .22 Hornet, or is a specialty reamer needed to convert to .25 Hornet?

	The nominal base diameter of .25 Stevens RF was .276". The measured base diameter of new Hornet brass from my larder is .293". What I would do is to swage the base of the Hornet brass down, using a .25ACP die. This isn't a lot, by comparison with some I've done, but it will leave a little fillet just above the rim, which would be turned off in a lathe. A drill press and a sharp file will do pretty well for that in a pinch. You'd need a good hefty press. An RCBS Junior would be about the minimum. If the BB has already been bushed, remove that bushing and make another one that aligns the pin for centerfire. This can be done on a drill press, but a small vertical mill is much better. Reaming the chamber presents problems. The .25 Hornet pilot won't fit for starters. The reamer would have to be held short by .690 to get the length right. Chamber will come out small, since the .25 Hornet case is tapered.

	Been there, done that with a Stevens Marksman; the whole story is in the June 2010 issue of the Single Shot Exchange, and last time I checked, they still had back issues. Use a .22 case for priming with reformed brass. Works just fine if the gun is in reasonably good condition.

Stronger than the Favorite. And it came in a centerfire version, too!

	I think I'll leave my Ballard in .25 Stevens as is. It was rebored by Stevens to the .25, and I've got 4-5 boxes of ammo. Not sure I want to go to this much changing to fire this one gun. I can shoot others, and leave it as a curiosity.

	Edited the Steps: Been many months and had to retrace my steps Here's the process I use to make 25 Stevens reloads: * Trim 1.403 length on 22 Hornets down to 1.130 * Run 22 Hornet brass in a 25 Hornet FL sizing die - to reduce the web * Run the cases into a 25 Hornet Expander die to expand the case just past the shoulder * Re-run the cases back into a 25 Hornet FL sizing die * Fireform the brass * Trim brass to 1.125, the case length of a 25 Stevens * Reloaded with either 7-8-9grs BP (original BP charge 10-11grs) and 3-4grs of 2400 smokeless using the Lyman 257420 - 72gr bullet Results that the reloads drop into the chamber with ease (You need to *Login* or *Register* to view media files and links)
