No, they are two different cartridges.

Bent_Ramrod, I shoot the shorter WCF version & was thinking I could,but this is my first foray into this caliber. Will the shellholder for the 25-20WCF not work?

Appreciate everyone's reply. Great forum. My other vintage calibers are more widely used; 25-20WCF, 32-20WCF & 38-55.

I bought a lee collet neck sizer for the Hornet and opened up the collet (and made a new decapping rod) for the 25-20 WCF. Works well. For the Stevens SS I made a spacer to go over the SS case to make up the difference in case length.

FWIW, Lyman's shell holder listing showed the #19 as being right for the 22 Lovell (22-3000) which is of course nothing but a necked down 25-20 SS.  My #19 fits my 25-20, but of course I have some random old WW and Rem-UMC cases that may not be typical of what you find.

Thanks guys. Been reloading since 75, 1975 that is. Depriming no issue as old Lyman decal rod with pin & holder inserted in case & gentle tap deprimes  & 223 shell holder for my Lee priming tool should work & bell & seat with 25-20 wcf dies. At least till I see if me & this gal are going to gee haw as my old Granpappy used to say.
Many thanks.

Scrounge all the shooting sports emporia, like Buffalo Arms, Graf’s, Huntington’s, etc.  there may be some leftover stocks of Jamison/Captech .25-20 SS or Basic Brass still around, but it is getting snapped up quick.

Haunt Gun Shows and Wanted/For Sale sections of shooting web sites.  Bertram Brass has gotten somewhat better over the years, although more expensive as well.

Rocky Mtn. Cartridge will turn you a handful out of bar stock, if you have the money.  It’s good stuff, but not being drawn, it will not go through sizing and expanding dies for very long, at least IME.  However, with a stop ring bullet like Westerner shows, or breech seating, or black powder, this won’t matter much.

It’s very weird.  For one brief, shining moment, .25-20SS brass was actually easier to find and cheaper to buy than the WCF version.  Then, poof!!
