Lubrication Care If You Have Trouble

Shown in Photo #31 are the lubrication points on the reloader. The loader should be lubricated about every 1000 rounds reloaded. Lubricate sparingly using heavy oil. (EP90 is ideal.) We do not like to see spray cans used to lube your loader. These sprays cause a buildup of residue over the entire loader.

Occasionally feel the inside of your crimp die, if you should notice any buildup of dirt or residue, it can be removed using a swab using any household cleaner.

Do not use any wet lubricants on any part of the machine that comes in contact with powder.

It is not necessary to have any extra equipment to process 3" shells. Start by installing the correct charge bar and bushing. Then deprime and resize and after repriming set the cases aside. After all your cases have been processed this far, remove the column bolt #611 A. Raise the column Vt, inch and now place the bolt into the top hole in the base and the top hole in the column. Tighten the bolt making sure that the column is square to the base of the machine. Now continue the loading sequence to finish your shells.

If you are going to load large quantities of 3" shells, we offer a number 63 kit which will extend the deprime resize and also the reprime so that shells may be completed in the standard sequence of operation.

1. Oversize shells

A shell that goes into your gun hard but comes out easy is caused by oversize plastic or paper.

In the case of plastic shells, overfilling is almost always the cause. To correct you need:

1. A case with more capacity

2. A shorter wad

3. Less shot

4. A more dense powder

5. Sometimes using more wad pressure will give more room in the case.

Over or under filling is most often corrected by using the proper size wad.

If using paper shells, any of the above can be the cause but the most common cause with papershells is to swell up by absorbing moisture. The only way to remedy this is to dry the cases before reloading, never attempt to dry loaded cases. Putting them in the oven at about 200° for 30 minutes will usually dry them. Don't even attempt to load paper cases during hot humid weather.

A shell that goes into your gun hard and comes out hard is caused by oversize brass. To correct:

1. Make sure sizing ring is resizing down to the rim of the shell.

2. Replace resize ring because of wear.

3. Make sure that your gun chamber does not have a buildup of dirt and rust.

Shells that will not go into the magazine tube on a pump or automatic are caused by:

1. Excessive resizing. Resizing shells often that have been fired in a gun with a large chamber tends to push material into the rim of the shell causing it to be oversize.

2. Adjusting the resize ring down to where it flattens the rim of the shell will cause the rim to be oversize.

Case bulges above the brass: When a case bulges above the brass, it is usually caused by overfilling the case. To correct:

1. Use a case with more capacity

2. Use a shorter wad

3. Use less shot

4. Use a denser powder

5. Use more wad pressure (40# is usually sufficient).

Can also be caused by cam adjustment or punch adjustment being too low (refer to adjustment instruction #5 for correction.

Poor Crimps

1. Hole in crimp Refer to punch and cam adjustment

2. Misfolded crimps Using wrong crimp starter 6 or 8 point. When using a six point starter put a mark on your star crimp housing and align the old folds with it.

3. Swirl in crimp Caused by cam adjusted down too far, refer photo no. 33 to cam adjustment #5 .

COLUMN BOLT

Measure sticks when dropping shot. Some of the causes are:

1. Large shot sizes (larger than #6)

2. Grommets worn

3. Reclaimed shot (contains small stones and no graphite lube)

When using large shot sizes, it usually works better to remove the grommet from the shot side of the measure. Moving the bar gently and reversing the action when resistance is noted usually works.

Shot lodges in tubes and will not drop into shell.

Thiscan be annoying particularly in the small gauges because of the small tube diameters when using heavy shot.

It is best prevented by raising the handle to the point where the rammer tube is just in the shell and moving the charge bar across very slowly so the shot does not all drop at one time which usually causes bridging.

Powder Leaks From Measure

Usually caused by not having brass washer in place when using Winchester Powder. Install per instructions at Photo #6, Page#5 .

This washer is placed under the grommet with the smooth side down.

Steel Shot.

This reloader will load steel shot.

Lead and steel are not interchangeable.

Kit #8433 is necessary to convert to steel shot. Do not use components designed for lead shot.

Do not use charge bars designed for lead shot. A special bar is necessary for steel shot.
