INSTRUCTIONS:
The PT-50-H fits the ram and press head of Corbins CSP-2 Mega-
Mite press, CSP-2H Hydraulic Mega-Mite, and CHP-1 Hydro-Press.
It is used by running the ram to its top limit,
and then adjusting the shell holder body
(during use) and the anvil screw and lock
nut (pre-adjustment, prior to use) to obtain
the desired primer depth. A hex wrench is
provided to adjust the protrusion of the anvil screw, from the base
end. This pre-setting is done first, and final setting is done by turn-
ing the shell holder body. The ram can be very slightly lowered, rather
than running it all the way down for each operation, to insert a new
primer and case. The end of the press stroke is used as a positive
stop, to prevent variations in seating depth due to slight changes in
the press stopping point.
CAUTION: These powerful presses can easily crush and detonate
the primer under certain circumstances. Never put any part of your
face or body over the top of the case. Do not attempt to prime loaded
cases! Serious injury or death can result from fragments of primer
or case materials expelled in the event of a detonation. Practice
seating empty, fired primers before attempting it with live primers,
to make certain of the adjustment.
Use the lowest pressure that will seat the primer consistently. Keep
the tool lightly lubricated with a rust-preventive lubricant when not
in use. Remove any lubricant from the inside of the shell holder and
the priming hole (where the primer will rest before seating) prior to
use. If a shell does not accept the primer with relative ease, the
pocket may be crimped or need to be reformed.
The PT-50-H fits the ram and head of these Corbin Swag-
ing Presses: CSP-2 Mega-Mite, CSP-2H Hydraulic Mega-
Mite, and CHP-1 Hydro-press.
