How to make 25-20 Single Shot (and 22 R2 Lovell and other derivatives) brass from .223/5.56mm brass

- This video describes how I've learned to make 25-20 SS brass from .223 brass. I rarely make any videos, and I even more rarely edit videos, so this isn't very well done, but I did the best I could with my very limited experience and knowledge of my video software. Some notes -
I wanted to put in some pictures with descriptive text, but I couldn't figure out how to do the notes with the pictures, so I just posted the detailed closeup still photos a couple times, with no captions.
When doing the pressing, I mentioned a couple times about "3000 pounds" or "3500 pounds" of pressure. I misspoke - that's 3 or 3.5 TONS of pressure I was referring to.
I wanted to speed up the tedious, repetitive lathe turning between about the 14 and 18 minute marks, but I couldn't figure out how to do it. You can jump from 14 minutes to 18 without missing much. Or set playback speed to 1.5x or 2x for that portion.
The pin that goes in the end of the punch and keeps the primer pocket from collapsing during pressing is a piece of 11/64" drill bit shank.
It would have been better if I'd filmed it at 1x instead of 0.5x, but I filmed it using a head-mounted iPhone attachment and it was very hard to tell where it was pointed, so I had to use 0.5x to make sure the subject was in the shot. So you don't get to see much detail when I am pointing out details, but hopefully the closeup still shots will compensate for that.
I also forgot to mention at the end, but once you've cut the neck off, you really should ANNEAL the case, especially if you plan to take the 25-20SS to 22 Lovell. See this video for the best and cheapest way to do your annealing:

Cool, about 25 years ago I had an R2 Lovell on a Winchester M54 action. It was originally chambered in 22 Hornet and the provenience I had was gunsmithed by Abercrombie and Fitch in 1936. It came with some brass. I scoured gunshows and eventually had about 40 rounds. It was a beautiful rifle and would make sub MOA groups at my100 yard range.
Thanks very much. The 7mm die info is greatly appreciated.
Would you consider selling a punch set? I recently bought an 22-3000 R2 in a Hepburn falling block action
I could make one, but the price would probably be unreasonably high, because I'd have to hand make it from scratch, and it would take hours. If you have a lathe, you can make one, and if you don't have a lathe, you won't be able to use this forming technique anyway. To make one, just turn a steel bar to approximately match the profile of a 7mm Mauser case. It doesn't have to be precise, but the closer you get the punch to match the profile, the less likely the punch will be to move around laterally inside the die. You could even try it with just a straight punch; might work fine, especially if you don't have a lot of slop in your press.
Could you send me some dimensions for your punch? And the primer stud
I need 25-20 ammo and I can't seem to find anyone who has it.
It's highly likely the only 25-20 SS ammo you will find is very old, vintage, overpriced, probably poor condition on GunBroker. Your best bet is to make your own.
Do you anneal just before forming with .25-20 SS sizing case?
It's a good idea to, although perhaps not necessary for 25-20. If you're going down to 22 Lovell, then yes, for sure. For by far the best bang for the buck in annealing cases, see the following video. One of many nice things about it is that you can also use the main tool for what it was made for - freeing nuts and similar.

@@TheClampetts I have sufficient G&H Lovell brass to carry me into the next life. For .25-20 SS not so well fixed. I have some Jamison, and have wondered if annealing might help it last. In the meantime I am reviewing friends' shops to see who has a 10-ton press.
Any preference about what make of .223 to use?
No - I've done it with new brass and I've done it with old Lake City milsurp brass. Either one squishes right down nicely. Just make sure it's CLEAN.
Just think... with all this high dollar equiptment, you can work day and nite for a month and maybe produce a dozen cases....WOW...!! ACTUALLY. It is easier to convert 32/20 into 25/20 with conversion RCBS dye set. ... if even you can find 32/20 cases.... Starline Brass used to have both, but are refusing to make more.... Boooo...!! On them...!!👎👎
Yeah, Jamison used to make 25-20SS brass and Midway and other carried it. But then Jamison went out of business, so that was the end of that. I got maybe 100 cases, but if only I'd seen the future better, I'd have bought thousands.
