Why can't 25-20 be formed from 357 max?

The nickel coating is so thin it doesn't really matter - but I would anneal, or you could get flaking of the nickel.  Neckturning isn't an issue either - actually makes for some pretty, two-tone cases... Wink

There is a lot of opinions but is there anyone that has actually formed 25 20 wcf from 32 20 nickel?  It would be good to hear from them.

The nickel plating is very thin and really just for looks.  Nickel doesn't tarnish easily so the 'brass' looks nice in say a cartridge belt.  I suspect that the nickel plating would eventually crack if the case was reformed a lot.  It might do so on the first forming if severe enough.  Think cracked chrome plate on an old bumper that gets dinged.  Nickel is also a bit harder than bass and might wear the die more but you aren't reforming zillions of these.  I would just go for it as the consensus recommends.   

BTW I can still find the odd box of Remington 25-20 WCF factory loads at $60 a box of 50.  I bought three boxes as brass backup in case I start wrecking cases.  PM me if you want me to look for those.  I will even pull the bullets and deprime if one wishes.  I'm not sure of shipping rules for loaded ammo. 

A bigger problem is getting powder; A9, AA4100 and Ramshot Enforcer all 'evaporate' off the shelves around here.

Doing a little tinkering today reforming some 222r brass I formed frame 357 max. Turned cases down .020 at web and ran through forming die I turned , and formed to the rim base. Think if ran through a 25-20 full length die it could work. Once formed it probably fire form ok.

I had two nickle .32-20 cases that I formed to .25-20 WCF. Both case separated the first firing and both were fixed loaded so I do not know how they might have held up when used as a breach seat case. Both cases were anneled prior to re-sizing.

Craig,

Have you had any all brass cases separate?   What load were you using.   

I've yet to have a case separate using 9.5 gr of AA-4100 including reformed 32-20 cases.  It sounds like all of the nickel won't hurt theories are wrong but two tests isn't much info.   

Dave

Hmmmm.  Me thinks that they should have been annealed both before and after reforming.

That is necessary for the 7mm IMHSA's that I reform from 300 Savage.  Just enough working of the brass to harden it.
