Yup.

I recon @The Heretic does as well.

Yup.

I recon @The Heretic does as well.

I hear it's tough to reload.
I'd be interested in trying this for my Enfield.

You have a 5.7 Enfield?!

Yes - I have thousands of once fired 5.7 cases - got almost all of them from somebody else when I bought a Five Seven pistol (as part of the the sale).

I have the dies, but since I also have plenty of 5.7 ammo and it is reportedly tricky to reload, I am not inclined to reload it - just set it aside. If someone would produce/sell a 5.7x28 single shot/lever/bolt action firearm, or a .223 -> 5.7 adapter, then I would probably try some reloads.

Somebody please make an adapter or rifle single shot/lever/bolt action firearm?

Yes - I know somebody makes 5.7 barrels for the Contender/Encore - but the platform is too expensive for my budget. Something like a Ruger American for half that price would be my preference.

It is convenient that the 5.7 case is .313". I imagine that the swaging die in the process sizes the 5.7 case to .311-.312". I would prefer .311" so that I could maybe use it in 7.62x39?

The 5.7x28 has a case capacity of 14 grains of water, I wonder how that would translate to lead mass? I imagine that bullet is plenty heavy, so it would be subsonic. Having a flat nose and strong brass case it would probably be non-expanding at almost and reasonable velocity.
