Sizing/Depriming Die
The sizing/depriming die is a full-length
sizing die, manufactured to minimum toler-
ances. We
strongly
suggest that a head-
space case gage be used to correctly adjust
the size die. Always clean and lube your
rifle cases before attempting to process the
cases (thru the size die).
1. Move the handle down to raise the plat-
form.
2. Screw the sizing/depriming die into sta-
tion one of your reloader.
3. When the die contacts the shellplate,
back the die off 1/2 turn.
4. Use one lubed rifle case to test your siz-
ing and headspace. Readjust the die as
needed to achieve proper headspace.
5. With a case in the die, snug the lock ring.
The depriming assembly includes a car-
bide expander ball for “squeak free,” effort-
less neck expansion. In the event of a stuck
case, the design of the depriming assembly
allows it to function as a stuck-case
remover. Simply remove the silver clip,
loosen the stem lock nut and then spin it up
to the top of the stem. With a wrench, turn
the depriming assembly into the die.
“Clockwise” turns will loosen the stuck
case. Use pliers to remove the case from the
depriming assembly.
Bullet Seating Die
Our bullet seating die is
internally designed to keep the
bullet straight throughout the
seating process.
1. Move the handle down, to
raise the platform.
2. Screw the bullet seating die
into the bullet seating station
on your reloader.
3. Put a sized, empty case into
the shellplate under the seating
die. Pull the handle down.
Screw the seat die body down
until it stops, then back it up
1/8 of a turn.
4. Refer to your rifle loading
manual for proper overall
length (O.A.L.) information.
5. Use only resized, deprimed cases when
setting this die. Move the case to the bul-
let seating station on your reloader
6. Place a bullet on the case and make one
complete stroke of the handle.
7. Check the overall length (O.A.L) of the
test case and bullet using a quality dial
caliper. Adjust the die up or down as
needed.
8. With the case and bullet in the die, snug
the lock ring.
Taper Crimp Die
The taper crimp die is configured to cen-
ter both the case neck and case body, there-
by aligning the entire cartridge for a more
uniform crimp.
1. Place the test case/bullet you have into
the crimp station on your reloader.
2. Move the handle down to raise the plat-
form.
3. Screw the taper crimp die into the crimp
station on your reloader.
4. When the die contacts the test case/bullet
move the handle up to lower the platform
5. Turn the die 1/4 to a 1/2 turn “clockwise”
and try crimping your test case/bullet
6. Use a quality dial caliper to measure the
case mouth diameter. Usually, a .002
change is noticed between the neck
diameter and the case mouth diameter.
Adjust as needed.
7. With the test case/bullet in the die, snug
the lock ring.
Refer to the machine operating manual
for any further instructions.
