4. Finish the draw. If you have a .224 jacket maker, the punch is one straight
piece and will go through the die. If you have a .243 jacket maker, the punch
is made with two diameters, and will NOT go through the die. To finish a .224
jacket, you must push it all the way through the die and out the top. To do this,
lower the ram and see if the jacket comes of in the die, or stays with the
punch. If the jacket stays with the punch, it will be ejected by the tube and
disk assembly on the down stroke, and you can push it through later with a
second operation. If it stays in the die, you can put the push rod into the
jacket, and shove on the end of this short (1-inch) rod to push the jacket all
the way through the ring die insert. It may not come out the top yet, but it is
drawn. The next jackets will lift it out. Catch the push rod so it doesnt drop on
the floor when you lower the ram. If you have a .243 set, you can use the
knock out rod and a small mallet or block of wood to tap the jacket back out
of the die (or, it may come back with the punch and be ejected automatically).
The .243 jackets are actually a kind of pre-form jacket. They are not brought to
.243 caliber in this operation. The mouth is flared by pressing over the punch
angle joining the two punch diameters, so that it will seal the bore of the core
seating die and hold the lead pressure during core seating, which will expand the
entire jacket to the correct diameter (just like blowing up a balloon, but with thou-
sands of pounds of pressure). Corbin Swage Lube is recommended to increase
die and punch life and lower the force required to draw the jackets.
Discard any cases which are bulged from oversized chambers, which have bad
firing pin cuts or split mouths, or have bad corrosion. Sort your jackets to that your
groups are fired using the same headstamps, and you will probably find the accu-
racy is improved! The thin rimfire cases require a slightly larger core seating punch
than a commercial jacket. They are very explosive and make excellent varmint
bullets. Accuracy is best if the velocity is kept under about 3,200 fps with most
rifles. Because the jackets are very thin, they dont like being fired at higher speeds!
However, with reasonable velocities, the .22 rimfire case jacket can give you a
virtually unlimited supply of free bulletsjust add scrap lead, swage them into
quality bullets using Corbin swage dies, and you can avoid the cost of commercial
bullets forever!
