That's cool and all, but with .224 bullets running about 10-12 cents each you'd have to make 10,000-12,000 of them out of completely free materials just to pay for the kit to make them with. And that's assuming you have all the equipment to cast the cores. If you have to pay anything for lead or anything else you'd have to make thousands more just to break even.
That was my conclusion as well when I first looked at those rigs many moons ago.
My first high-power rifle was (and is) a Remington 700 in 6mm Remington.
The gunsmith that sold it to me was also my reloading guru and taught me bottleneck rifle reloading with it.
The price of 6mm bullets back then was not outrageous but the price of the Corbin kit was.
My press is a Redding Ultramag and should handle the chore but the actual amount of shooting
I did with the 6mm did not come close to warranting the expense of the swaging stuff.
It does look like fun I'll admit but so does casting and I never quite got started with that either.
I could see the need to swage your own if you had something with an obscure
or obsolete bore where bullets were basically unobtainable.
Some of the folks in a double rifle forum I am in delight in bringing back to life old black powder euro guns.
Several of them have taken to making their own bullets to do this.
Several of them are a lot wealthier than I am too.
Corbin does have a huge set of documents available for free and one of them is the current price for the kits we are talking about:

They want $975 plus shipping for the reloading press version.
$1873 for the Corbin press version!
Holy budget busters Batman!
You can get a nice gun for those kind of prices (or a couple pounds of powder).
