Making Your Own Bullets

[sup][/sup] remenber lead is soft even up to 6 percent it will flow with the amt. Of pressure from the punch and shoot like hell i did a lot of jt.
 
Bill are you telling me you make a 222gr 7MM Match bullet???

I don't own a 7mm of any sort but I'll build one to try out a 222gr bullet.
 
And as more than one bullet maker has found out, simply speeding up
press cycling does not always work.
The core needs some time to flow under the pressure from the die.

You are moving lead by pure mechanical force.
There are real reasons the presses are so massive.
You do not want the 'line loads' between the parts to be to short.
Think of a pin rotating in a hole.
The contact ares is a line along the length of the pin.
Exceeds the strength of the pin or hole and things start to permanently deform with each cycle.

Let alone the actual surface wear fro friction between the bullet and the parts themselves.

The double action of the link in the press allows the leverage length to approach 0, the lever arm is constantly decreasing.
Eventually it passes though zero creating infinite mechanical advantage.
It is limited by the strength (compressive) of the materials used to make the press linkage.
That is why holes and pins must be hardened.

CELLAR WATCH HIM MAKE CORES ONE AND
HALF PUMPS MADE PERFECT CORES=BA SOME YRS I MADE
20 CORES BOILED THEM DRDED WITH FAN
CORESEATED POINTED LOAD SHOT RIGHT
AWAY AND SHOT ZEROS AND ONES GEERLY I BOILED
20 MINUTES RINCED LET SET OVERNIGHT
