Yes swaging seems to be a dying art or the reloading faction. It was going pretty good back in the 60 to early 80s and then kind of petered out.
But I'm all for it because you can come up with some interesting concepts in bullet weights and shapes.
Of course it doesn't hurt to have a mini-lathe to help you fabricate nose punches and other parts for swaging dies...see attached image of C&H swaging dies. These are extremely hard steel dies made by an old firm that knows how to make them for nearly a half a century.
Note the nose punches below each swaging die, these have different ogive shapes in them to facilitate the shape received when you ram the nose punch on your press up into the swaging die.
The 101 die set is two dies, one is for swaging bullet nose shape and the other can attach a copper jacket and give you an ogive round nose shape to your bullet with a small mep flat at the top.
I am presently doing .44 caliber and .45 caliber. The .45 caliber is for an older S&W that has extremely large cylinder throats and I am able to make lead or jacketed bullet diameters read from .451
to .454 or even .457 diameter.
It also helps to have a Lyman or RCBS bullet lubebrisizer press so you can apply bullet lube to your swaged bullets base lube rings.
I recomend C&H tool & Die'4-D out of Mt. Vernon Ohio as the best price and quality of swaging materials.

I hope that addy works for you.
Check it out its an interesting way to make bullets.
