Adj. Length Punch, -H (<= .375)
Quantity in Basket:
Catalog No.: PUNCH-HA
Shipping Weight: 0.50 pounds
The adjustable PUNCH-HA (at or under .375 caliber) is used
in the JM-1-H jacket making die (1st die of the CTJM-1-H
tubing jacket maker set) when you want to make several
different lengths of jackets. An adjustable sleeve around
the reduced center portion of the punch can be set for
different lengths of tubing.
Adjustable core seating punches are used with copper tubing
jackets or with any rebated boattail bullet, to prevent
stretching the jacket when the base is being formed. The punch
shoulder can be set to the length of jacket, so that the
jacket cannot extrude forward as the core is seated.
Adjustable internal punches are used with the point form
die, to seal the die cavity at the top for making a clean
flat tip bullet in one stroke without using a lead tip
forming die, or to seal the die so that it can be
pressurized to swage lead bullets and adjust the weight with
bleed holes in a point form die. This is often used for
shoulderless paper patch bullet swaging, eliminating the
core swage operation.
It is helpful with tubing and core seating punches to
specify the maximum and minimum expected length of jacket
to use, so that the die-makers can evaluate the range and
see if the punch can adjust that far, or if you would need
a second punch to cover it. Another option is a different length of adjustable sleeve for the same punch.
For larger calibers, use the PUNCH-HL (over .375 diameter).
