As my post title states, it's either going to be 25 projects that I share, or projects in '25...

For openers, I'm revisiting a project that I started some time ago but never finished, was it in '23 or '24, I don't recall, it's been a blur.  It's one of the Storie Worn Ballard castings.  Originally I planned to make the one I had into a 22rf but plans change.  I purchased a few of the Worn castings before Rodney quit this venture and there's one a bit different that will be my 22rf.  Maybe it will be one of the 25 posted here.  The new caliber choice for this action at the moment is going to be a 25-21SS, (another 25 to go with the post title) Here's pics of a dash back to the breech block build and forward to current action status.  The plan is for it to wear a GM barrel, one that was already run through the mill last winter, I think.

Along the way I picked up a 25-21SS reamer and dies but not much for brass.  I think 20 pieces were purchased from RMC but I guard those close being the tite-wad I am.  I've turned a few from stock for one of my other rifles and I've traveled down the road of nibbing cases in the lathe, it's all labor intensive with marginal results.   
I bought a batch of 223 Basic brass from Starline in the past  and dabbled with them making 25-20SS but never got the sequences right for a good case.
I returned to George Nonte's book a few nights ago studying his description for lengthening brass cartridges.  He explains his method of enlarging the brass and using for lack of a better word, venturi effect to extrude it.  I spent a few late evening recently and tried several different methods, finally getting one to work.  There is a pile of scrap getting to the ends, but here's a few pics showing the dies I came up with.  At the base is a ring, that has the "venturi" cut in it, a punch that presses brass into that ring, a spacer that holds the punch at it's critical location and then a pusher rod that moves the brass through the ring.   
Pushing the Basic brass one time through I get a length increase of .100".  When the brass is swaged into the 7mm mauser die to start the initial 25-21 forming process it grows another .085".  In the final stages of forming in the 25-21 die itself, another .075" is gained in length.  From the original Basic  223 brass it makes a case for my 25-21SS that falls short of spec by only .025".  For now, I plan to shoot this cartridge breech seated and it's going to work fine for me.
