Swaging jacketed bullets?

Not my proper Corbin SWAGING dies (been doing this for over 30 years, not just reading about it)

So, what you are saying, with your 30yrs of doing this, is that, with your proper Corbin Swaging dies, you can take a factory .321" jacketed bullet complete and stuff them into a .312" Swaging die and turn out a perfectly formed bullet with no separation issues? Help me out because that's not how I understand the process of Swaging bullets using Corbin dies, jackets, and lead wire. And since, under such high pressures, metal flows like liquid, how do you keep the two metals separate and not becoming some sort of non-analogous mixture?

I enjoy the difference between theory and reality.. This difference has sold a lot of shooting supplies over the years. When a 7x57 and a6.5x55 are both reliable moose killers, there is probably nothing you could do to a 250 gr + bullet that would make the moose feel safer.

Bullet reducing dies are draw dies and work well only within a range of about 0.006". Going past this limitation will cause bullet distortion, lead core and copper jacket need to be be drawn out evenly or some wild exterior ballistics will occur. These bullet reducing dies are open ended and designed to feed through the die. Pushing over-sized bullets into a closed die results in broken dies. Draw dies are built to hold larger jacket or bullet will reduced diameter centered in the die.

I know. Tell that to A&Shuntr. He's been doing this 30yrs with Swaging dies.
 
OMG, When bullet makers refer to closed dies they are not a one ended piece of steel (how would you get the projectile out?). They support the whole bullet, ogive and all. The die has bleed and ejection holes. This is where experience comes into play, if you care to call up Corbin and spend several thousand dollars and actually do this you will understand the process first hand.

This reminds me of a old saying my Grandfather once told me: Those of us who can, do. Those of us that can't, teach.

Draw dies are open ended only. Core swage dies are closed dies as the internal punch inside the die holds bullet in place while it is expanded or swaged, the die will break at some point if enough pressure is applied and without any damage to internal punch. Lead bullet or core dies have bleed hole or holes to uniform mass. In theory the point form die is open ended because the external punch is withdrawn from die as point is formed, and its only purpose is to eject bullet from die on down-stroke.

I don't recall having you over to my place to inspect any of my over 500 dies (reloading, hydraulic bullet making, and bullet re-profiling dies) that I have used over the years. Nor have you observed any of the processes I use. Yet you insist on the illusion of knowing my exact equipment. That my friend is PFM, Pure F___ing Magic

A book told you this?
In all my years of swaging, I have never seen copper, brass or lead flow like liquid. Without heat.
It is not those that can't do, teach. It is those that read books but can't do, think they can teach.
