"Fire Forming" Brass???

Well lets see if this works, the computer is much harder to run than a dividing head. The big piece with the shell sticking in it was my first die....a 38-72 winchester. the die is soft steel so I made it beefier. The others were made from grade 8 bolts which is super tough stuff. they include 358, 40-82, 303,25 ackley krag and so on. to get zero head space you chamber the die so the shell is flush with the bottom of the die. As you see in the pictures there is a bushing that goes into the die receptical and is fitted over the firing pin. insert the case to be formed into the die screw it into the recepticle, hold it out at arms length pull the stiker back, release...and kaboom (hearing protection required) also I might ad under no circumstances should this tool ever be fitted with live projectile ammo, it would be bad very bad. the design is strait forward and tolerences are relitive to what you want. The main spring on mine is from a hi-power recoil spring

Happy forming

If you don't have the tooling, George Nonte used an old receiver (with stock...) and cut down barrels.
Such short barreled contraptions are of course prohibs in Canada, but an old junker in 8mm with a good chamber would do.

Nonte might also have been the one who argued that water under pressure would also work, in a device similar to the one used for Berdan depriming (hammer+punch+die).... if you live in a non-leaky condo...
