It is simple enough to swage 22 or 25 caliber bullets from lead wire.  Cut the wire to length with something like an old fashioned paper cutter.  A heavy duty reloading press has plenty of power.  No hydraulic stuff necessary.  You might get started if you found a set of the 1940s era dies for making 22 cal jacketed bullets. The problem comes if you decide you need grooves to hold the lubricant.   

There are firms who will sell you a lot of stuff, but small bullets can be done with simple muscle power and not a lot of it.

      Charlie Dell used to cast bullets, lube them, then "rectify" them in a swage.   I think that this was because the alloy he was using, ca 1% tin, was so lean that it was hard to cast bullets without internal voids.  After casting, he would then heat-treat the bullets to the desired hardness, then lube and swage.
      There was quite a fad, 60 years ago, of swaging half-jacket pistol bullets, and I have used one of those presses to swage various non-grooved 38, 40, and 45 caliber bullets from cast blanks, for paper-patching.   Never tried the smaller bullets, myself.  Part of the attraction of using one of these presses instead of the common loading press is that they have a built-in ejection apparatus.  It works fine to use the cutter for the swage to make the bullet mould for the slugs, as the resultant shrinkage gives you a slug that drops right in and only requires a little push to swage to final shape.   
       Probably some ticklish machine work to make dies as small as 22 caliber, tho.

Cat  Whisperer...Sounds like your a man after my own heart in wanting more uniform .22 cast bullets.  Here is what I did to achieve that very same goal.  I sent Corbin Mfg. samples of cast .22 bullets I wanted to uniform..These were Ideal 225415..(older circa 1960). 1980 225415, Saeco #22, & Eagan MX.  These had proved accurate in a custom Sharps Borchardt Hornet & Ruger No. 1 .222  Rem.  I had Dave make up 7/8X 14 reloading press type swaging dies in .225 & .226 dia.  I asked for nose punches in flat, round nose & truncated flat nose shapes.  I asked that bottom edge of punches be radiused slightly & made oversize in dia. so as not to dig into cast bullet nose.  
    In use, after inspecting, and installing gas-check, I like to impact lube with Moly in vibratory tumbler.  After this, they are lubed & sized in .224 die.  In swaging, only enough pressure is applied to insure gas check is square with base & bullet body..while you can swage for a sharp gas check edge, I find it more accurate to leave a slight radius.  I usually apply pressure for 5 sec., release & re-apply for 3 more..seems to make them more uniform.
   Using the truncated point punch, the Eagan MX comes out looking for all the world like a Remington Yellow Jacket .22 L.R. bullet.  I can make the .225415 into a nice long R.N. shape..or using a flat punch, keep original shape.  The Saeco when swaged to either R.N. or tapered flat point will group in either the Hornet or .222 to rifles full accuracy potential with best match jackted bullets.  These dies & punches are kind of pricy..but the improved accuracy possible makes them worthwhile to a real rifle loony.
