SHOTSHELL RELOADER INSTRUCTIONS To help you load completely satisfactory ammunition the first time you operate your 366 Auto, these instructions have detailed steps of operation and adjustment to help in avoiding problems. To begin loading shot shells, you will need powder, shot, primers and wads, in addition to empty hulls. Before purchasing any of these components, first note what charge the standard bushing furnished with your loader will throw by weighing your charge.
SETTING UP YOUR 366 AUTO Mount your 366 Auto securely toward the front of a sturdy bench. All operations of the press are to a full stop, so the operating handle must clear the bench when in the down position. Since the shells are ejected down a chute, out the back of the loader, you may want to set your loader up on riser blocks (010060) to provide access to the completed shells. An alternate method to catch finished shells would be to cut a hole in the bench and place a box underneath. 1.
FUNCTION AND ADJUSTMENT Fig. 1: Function and Adjustment The following is a detailed description of the operation and adjustment of the 366 Auto Reloading Press. This press has been pre-adjusted at the factory for Remington STS cases, but every person has a preference about how the finished product should look, so some changes might be necessary. The reloader should begin by advancing a single shell through each station to familiarize himself with the operation and adjustment of each position.
Step 1: STATION 1A (Resize and Deprime) Fig. 2: Resize and De-Prime Place an empty shell in Station 1A, making sure the deprime punch enters the case mouth and the shell is reasonably centered under the size die (#14). Pull the operating handle (#37) to the bottom of the stroke. Make sure nothing interferes with the handle reaching bottom. When the operating handle is pulled, the platen casting (#107) rises until the eccentric arm stop (#111) contacts the base casting (#100).
Step 2: STATION ONE (De-prime Only) Fig. 3: De-Prime Insert the case in station. 1. Normally, at this time, we would fill the primer tube (#2), but since we are working with a single shell, drop only one primer from the tray (#1) into the primer tube (#2). Now pull the handle (#37). As the handle (#37) makes a complete cycle, the shell will automatically advance to the next station also dropping the primer into the hole in the primer seat pad (#3).
Step 3: STATION TW0 (Prime) Fig. 4: Prime Pull the handle (#37) through a complete stroke. The primer seating punch (#20) or the optional spring loaded primer seater punch (010051) will enter the case and push the case down, over the primer in the primer seating pad (#3). On the return stroke, the primer seating pad (#3) will push the case back up into position and the shell plate (#45) will advance to the next position.
Step 4: STATION THREE (Drop Powder) Fig. 5: Powder Drop Before pulling the handle (#37), pull the powder slide (#69) toward you. The spring (#71) will lock the slide in place in the second slot of powder slide (#69). The powder drop is now on. During the stroke, the powder bushing will advance to the Powder Drop station. Normally, we would leave the powder slide on, but since we are taking one shell through each step, push the powder slide back and shut off the powder.
Step 5: STATION FOUR (Wad Seating) Fig. 6: Wad Seating Insert a wad in the wad guide (#106A). Pull the operating handle (#37) through a complete stroke. When the handle (#37) is pulled, the spring (#106B) around the wad guide rod (#105) turns the wad guide bracket (#101) to align the wad with the case. The unit then rises until the wad is stopped with the platen casting (#107) by the wad ram (#48).
Step 6: STATION FIVE (Shot Drop) Fig. 7: Shot Drop Before pulling the handle (#37), rotate the shot shut-off (#70) backward, turning on the shot. Now, lower the handle (#37). The shot drop tube (#47) enters the case mouth and then both case and shot drop tube (#47) rise together to the top of the stroke. In this fashion, all the shot enters the case without being spilled. No adjustment of this station is possible. Upon completion of the stroke, the shells will advance to the next station.
Step 7: STATION SIX (Crimp Start) Fig. 8: Crimp Start As you lower the handle (#37), the shell at Station Six enters the crimp starter (#82). The plastic body has ridges on the inside to align with the old crimp and restart the folds. The outside of each crimp starter (#82) has a ridge corresponding with the inside, so if manual alignment is necessary with damaged crimps, follow these ridges. A hole in the case mouth of ¼” should be left when the shell completes this station.
Step 8: STATION SEVEN (Crimp) Fig. 9: Crimp As you pull the handle (#37), the shell in Station Seven will enter the crimp die (#59). The shell will contact the inside of the die and raise the die body (#59) as it goes up. It will then contact the crimp plunger (#58) and the crimp will be closed. On the return stroke, the shell will be pulled from the crimp plunger (#58) but the crimp die (#59) will keep pressure on the case to retain the proper shape.
Step 9: STATION EIGHT (Taper Crimp) Fig. 10: Taper Crimp The taper crimp is a smooth crimp starter (#82) and will taper the finished case better than factory loads. As the shell at Station Eight enters the taper crimp die (#59), the mouth of the shell will be “rolled.” On the return stroke, the shells advance, but the shell in Station Eight contacts a cam in the platen casting (#107), moves to the left, and drops through a hole in the platen casting (#107) down the chute (#108) to the back.
ADJUSTMENT OF AUTO ADVANCE Fig. 11: Adjustment of Auto Advance When the operating handle (#37) is pulled all the way up, a spring (#98) swings the pivot arm (#85) and the advance pawl (#94) to your right. The hook of the pawl rides in the gap between the shell plate (#45) and the shell plate ring (#110). On the return stroke, the roller on the base casting (#100) contacts the curve on the pivot arm (#85) and the entire unit is cammed toward the left, advancing the shells to the next position.
TROUBLESHOOTING Handle will not come to bottom of stroke Do not force the handle (#37). If you meet with any resistance, shut off the shot and powder and slowly return the handle (#37) back to normal while unlatching the rotating pawl (#94). 1. Check to see the loader is mounted near the front of the bench, allowing the handle (#37) to come completely down. 2. Check to see if the size die body (#14) adjustment has changed or if the size die ring cap (#19) has loosened. 3.
4. Check the wad guide bracket (#101) to see that the wad guide return spring (#106B) is attached and that the bracket is fastened to the wad guide rod (#105). 5. Check the charge bar cam (#9) adjustment to see that it hasn’t slipped. 6. Check for an obstruction, spilled shot, etc., between the shell plate ring (#110) and the platen casting (#107).
swinging wad guide (#101). You may have to cut the wad in half if it cannot be pushed through into the case. 1. Check your operation of the tool, making sure you allow enough time for the wad to correctly align with the ram. The wad guide (#106) should be set to swing out just far enough for easy insertion of the wad; swinging too far will delay the bracket. 2.
e. Double-check all components to make sure they are the correct ones for the specific load. f. Check adjustment of crimp plunger (#58). 3. If the finished shell does not have enough taper in the end or is flared, lower the taper crimp die (#82) (Station Eight). 4. If crimp isn’t deep enough, turn the crimp plunger (#58) in the final crimp down. 5. If the shell swirls in the center, the plastic shell has elongated or stretched. No adjustment is generally possible to remove the swirl.
