Hi, Thought I would share my project in swaging .22 RF cases to projectiles for my Baikal single shot .223.
I have two hand dies.
The first has 4 holes. the two holes on the left are my de-rim and sizing dies. The two on the right are my different shaped pointing dies.
The two on the left are stepped, the top half of each hole has a diameter to fit the .22 rim.
I firstly anneal the jackets with a small prop. torch. I need the whole case and rim soft as.
The bottom half of each hole has two different sizes allowing me to tap the rim out into a cup ( similar to a Lee handloader deprime rod) in the first and then size the new jacket to .224 in the second. The tapping rod has a rounded face so the brass isn't cut or damaged and is the exact size of the internal jacket diameter.

The longer die with seven holes ( below) allows the cups to be seated exactly for lead poring or cold swaging in a lead core. The other side has smaller holes for the hot pour.
So far I am experimenting with tapping no.8 lead shot into the case before pointing. This shot squashes and molds into the case actually forming a solid core.. surprisingly :o

I guess they will be more semi wad than spired but I will use them for reduced loads at around 2300fps using Alliant 2400 powder.
The 2400 works really well at 100m after 30 test shots with commercial 55g.
I Know, I know.. lots of work for small projectiles but I like to do it and rimfire brass is free on the range.
When I finish the lead stage and pointing after the weekend Ill post some pics and let you know how they perform.
At least beer can sized groups I hope at 100m.:-D
