Dillon 1050 Toolhead

chart on page 19 for the caliber you are loading for.

Loosen the lever arm bracket screw (#13732) and slide the bracket assembly up four inches and lock it in place.

Raise the operating handle, remove the two primer feed body screws (#13363) and lift the primer feed body assembly (#20773) off.

Remove the ratchet cam (#11686) from the toolhead (#20420). Fig. 19

Remove the mechanical return rod (#13960) from the powder measure bellcrank (#13871) by releasing the rod clip (#13929). Fig. 20

Read complete toolhead and shellplate removal instructions before proceeding.

Remove the casefeed tube (#13761) place it on your bench and take the toolhead off. Now you can remove the shellplate locknut (#20311) by loosening the four lock ring screws about four complete turns. This will allow you to remove, and replace, the primer slide (#20318 - large or #20317 - small); bushing (#13031 -large or #13222 - small); spring (#13858) and punch (#12849 - large or #13307 - small) with the replacement parts for your new primer size.

You should clean your machine at this time. Note that there is a specially designed screwdriver supplied for the bushing (found in your accessory bag). Prior to installation, lube the base of the primer punch. Now adjust your new punch (#12849 - large or #13307 -small) so that it is flush with the bushing (#13031 - large or #13222 - small) by turning set screw (#13226) up or down. If the primer punch is too low, dirt will collect on top of it leaving imprints on your primers. If it is too high it will bind the slide. Note: You can use the slide for a guide. Slide it back and forth over the bushing to check your adjustments.

Toolhead Removal

Disconnect the mechanical return rod (#13960) from the bellcrank (#20319) by releasing the return rod clip (#13929). Fig. 20

Lower the handle and remove the toolhead ratchet (#11686). Fig. 19

Remove the Primer Early Warning device. Remove the primer slide lever assembly (#20488).

Fig. 21: Use a 15/16" socket wrench to remove the toolhead bolt.

Obtain a 15/16" socket or wrench (not supplied) to remove the toolhead bolt (#13342) and washer (#13449). Fig. 21

Now remove the toolhead (#20420). Due to being spring loaded, there will be some resistance. Wiggle the toolhead up and off while holding the handle.

After removing the toolhead, carefully lower the handle.

When reinstalling the toolhead bolt (#13342) turn it in only finger tight then cycle the handle up and down to make sure everything is properly located. With the handle in the down position, tighten the toolhead bolt with the above mentioned wrench.

Shellplate Removal

Remove the ejector tab (#13189).

Loosen the four locator tab screws (#13895) about two full turns.

Use a toothbrush to remove any powder that may be in the threads before removing the lock ring.

Next remove the lock ring (#20311). Now push the casefeed plunger back (#13073*) and lift the shellplate (#11925) off. Be sure to lightly grease the bore of the shellplate when reinstalling it. Rule of thumb: turn the lock ring down until tight then back off one-eighth of a turn. Then tighten the four locator tab screws (#13895).

Casefeed Plunger Conversion

When changing calibers it may be necessary to replace the casefeed plunger (#13073*).

To do this, remove the clear casefeed tube (#13761) and pull out the colored casefeed adapter (#13654*). The adapter is taped for shipping purposes.

Remove the two housing screws (#13815) and the casefeed adapter housing (#13534).

Fig. 22: Be sure to lightly grease the plunger and roller after cleaning.

Place your hand on the plunger while removing the roller bolt (#13333). This will prevent the casefeed plunger and spring from jumping out of the machine. Fig. 22

Thoroughly clean the track and casefeed parts with a solvent. Now very lightly apply grease to the sides and install the proper size casefeed plunger (#13073*). Remember to grease the roller (#13498) and the roller track and Loctite the threads on the roller bolt (#13333).

Install the casefeed housing and insert the proper size adapter (#13654*). The casefeed tube (#13761) should now be inserted into the casefeed adapter (#13654*). Note that the tube is marked "up" on one end. Press this end into the tube clip (#13859). See the Trouble Shooting section for any adjustments.

Die Adjustments

Sizing Die Adjustments - Station 2

With the toolhead in the down position, screw the sizing die down until the bottom of the die touches the shellplate. Raise the toolhead and insert an empty case into the shellplate. Now, lower the toolhead down all the way over the case and tighten the die lock ring on the sizing die. The process described above will insure the die is centered correctly in the toolhead when it is locked in place. A note of caution: Never attempt to deprime a live primer. An explosion may occur.

Expander Die Adjustments - Station 3

Install the expander die (caliber specific) at station 3 of the shellplate. Place a case in station 2 and cycle the operating handle once (sending the case to station 3). Turn the expander die down until it makes contact with the case and cycle the operating handle. Make adjustments in one-quarter turn increments until the desired bell is achieved. Tighten the die lock ring.

A properly belled case should show a slight flare at the case mouth.

Seating Die Adjustments - Station 7

Screw the seating die into Station 7 with the appropriate seating stem installed. Each die set will include seating stems to fit the most common bullet types. Use the nose of the bullet to see which seating stem fits best.

Refer to a reloading manual for proper bullet seating depth or over all length (OAL).

With the handle in the down position, screw the seating die down until it makes contact with the shellplate. Then turn the die counterclockwise four full turns. Raise the handle and place one of the cases charged with powder into Station 7. Place a bullet on the mouth of the case and cycle the operating handle.

Inspect the bullet for seating depth (OAL) with a dial caliper or case gage. To make the OAL longer, turn the seating die counterclockwise in small increments. To make the OAL shorter, turn the seating die clockwise in small increments.

When the OAL is correct, tighten the die lock ring with the operating handle in the down position.

Crimping Die Adjustments - Station 8

Screw the crimp die into Station 8. Screw it down until it is flush with the bottom of the toolhead. This is a good starting point for the crimp adjustment.

Place a cartridge with a properly seated bullet into Station 8. Raise the platform and continue to screw the die down until it touches the cartridge.

Lower the platform and give the die an 1/8 turn down, again raise the platform.

Lower the platform halfway and inspect the cartridge. If the bell is still present, or the desired amount of crimp has not been achieved, give the die a 1/8 turn down and try again. Continue making small adjustments to your crimp die until the desired amount of crimp has been achieved.

Once the adjustment is complete, place the case back into Station 8 and raise the platform. Using a 1-1/8" wrench to turn the lockring and a 7/8" wrench to hold the die body, snug the lockring.
