Thread: Making 25 rimfire reloadable brass

If a good 25rf pops id possibly be twisted into another rimfire
But the smallest caliber I own now is 6.5 Grendel

Well I dug out the 25 RF Stevens favorite I brought for parts last year ( or might not have looked at the caliber markings well enough) and cleaned the barrel to see if it was worth fixing for you

IT IS NOT

Hi i just measured the .25 cal airgun H&N HP slugs = .250 x 32 grain
i believe with a swift kick up the bum these will expand and seal the barrel [ soft lead ]

@AR7 I have 100 of the 36 grainers coming
But sadly Via Aramex so slow or lost if previous parcels are a guide

Hi have you considered to use 25 cal gas checks on your slug gun lead projectiles

@AR7 I made a top punch yesterday to fit the gas checks in my lube sized and now that I don't have a mould I will try on the slugs

Hi Akaroa 1 when you made your brass from the 22 Hornet did you noticed it varied in O D size some
i my have to thin the case @ its opening to accept the projectile without bulging a tad

Sorry wrong photo

Yes I had to inside neck turn some cases .
But that was more to do with variation in bullet diameter with bullet types and powder coatings

The 25 RF is a very small case and forming it from 22 Hornet means there is a lot of brass being moved around.
So neck thickness was always going to be an issue.

What a grouse outcome.

have yo useen the way they redo rimfire priming??? super cleaver

Hi Thanks for your thoughts and info .Have being thinking along those wildcat [mild pussy ]myself.
just ran the 22 Hornet through the 25 acp die ,just a skim on the lathe to tidy up at the rim end .
But if we expand the 22 part of the Hornet to the 25 cal size we get about 36mm in total length
which is twice the cap. of powder vs the 25acp ..Leaving a rim @ the Hornet size makes it very easy to extract [my gun smith would like this ]
Cheers to all

I have thought of doing something similar with an offset priming blank for my .56 Spencer but care would have to be taken for correct alignment with the firing pin for every shot.

@gundoc a friend had asked me to do this for a 56-56 Spencer carbine he has
I just haven't had time to look into the parent case that it could be done with.
But it's the same basic technique that's used to run original kammerladders as well

Actually I think with a bigger stronger parent case it would maybe be a lot easier that dealing with this very thin and fragile 25 RF brass

And clearly the use of the Spencer's magazine is no longer an option due to timing the primer on to the firing pin

I would be making solid turned cases for it. The magazine could be used with a visual alignment check before fully closing the breech. The other alternative is to make a set of forming dies and make drawn rimfire cases out of copper sheet, followed by the aggravation of making a priming compound. I am not that desperate yet!
