	Bought a 44 in 25-20 recently. Realized it had been fooled with I got it home. Only paid about $100 so it's not going back. Shot today and the bullets tumbled. Fired cases show the shoulder tapered out. No neck. Bore is a little oversized and looks good. I'm wondering if there is a longer case that would work better. May just have to breech seat and load black powder hoping for a bump up in size. Bore measures .260 in the throat.

	What cases did you use in your test firing? 25-20 Stevens SS or 25-20 WCF?

	Wcf cases with the bullet loaded out front lube groove showing. I may cast some harder bullets. See if I can't get them to drop oversized.

	My guess is that you are shooting an original 25-20 Stevens, not one made for the WCF shell. Find some 25-20 Stevens cases. My new Graf's catalog lists Jamison brass. It is good stuff. You should not need hard-cast bullets.

	How do you get a 25-20 WCF case to go into a 25-20 SS chamber?

	May be a .25-20SS that someone ran a WCF chambering reamer into. Thus the chamber would be too long for the WCF making for all kinds of loading inaccuracies. If that is the case the only solution is to set the barrel back and rechamber to either .25-20 WCF or .25-20 SS. Of course IF that is what happened. I have found that the usual Stevens .25-20 groove diameter was .2585

	It is a 25-20 ss that was reamed to wcf. The chamber now is too big for ss brass. Wcf is too short for the chamber. I'm thinking breech seat but probably can't use black. Too much space between case end and bullet base. As now the bullet dropped into the breech is as deep at the base as a wcf case is long. Sleeving the chamber might work. Too bad there is not a suitable case that could make this work. Might have to reline. Or could re barrel to 25 hornet or 218 bee.

	There is one case that could fill your chamber to the end of the ss neck. The 32 Ideal but, they are not easy to find and expensive if you do find them. The 32 Ideal case has the same basic case head as the 25/20 - 32/20 Winchester and is 1.77 long. Frank

	There was a .25 wildcat based on the .32 Ideal case. The brass is pretty easily made from 5.56x50R, (the rimmed version of the .222 Magnum). If you can't find that, P/M me. EDIT: Occurred to me much later to just run the .32 Ideal into a .25-20WCF die and you get a long-necked 25-20 WCF. Looks a little funny, but I have the same sort of thing in my .22-20 Harwood Hornet, and it works just fine.

	Fifty some years ago I too acquired a Stevens 44, a plain-jane model, marked .25-20. Back then, shooting the gun as a .25-20 SS was not the best option, especially because my knowledge and resources limited me to easily-acquired factory-loaded ammo. Therefore on my family's yearly vacation to Chicago, I took the rifle to a gunsmithing firm recommended by my uncle to do with what they could. The gun was ready within a month and I was billed (a very reasonable amount as I remember) for "rechambering to .25-20 WCF". Now in hindsight, here's where the story gets interesting. The barrel was not set back. The chamber area looked normal. And the rifle was accurate enough at 50-75 yards for the plinking and hunting I did with it. So what did the magic men in Chicago do? Sleeve the chamber? Bill Lawrence

	If one sleeved the chamber to the full depth of the .25-20 Stevens cartridge, (1.63"+), then reamed it so there was .300 of .257" diameter freebore taking up the difference, it might work. Why anyone would do that when a barrel setback of 5/16" would do better and be a whole lot easier is beyond me.
