It is strongly advised to check all charges (powder & shot) with a reliable scale.
The adjustable shot cavity has the added advantage that one can easily adjust the given setting to
compensate for the different shot sizes and shot qualities on the market, in order to get the exact
payloads wanted.

Please note: When using any shot size larger than #4, sizable variations in charge weight are
likely to occur. With a large diameter shot pellet such as #2 size, heavy tool vibration becomes
necessary in order for the shot cavity to fill completely and uniformly, particularly with charges weighting in excess of 1 oz.
Starting with the warranty # 250,000 every Universal Charge Bar comes with a SHOT-VALVE that
has a recess (like mushroom-shaped) near that end, which forms part of the shot-cavity. This recess
will accept a choice of three mushroom-shaped inserts:


-Zinc insert uses for Lead-shot

-Black plastic inserts uses for bigger Steel-shot like #2, #3…and Brown insert uses for smaller
Steel-shot like #8, #9….
The plastic inserts can also be used for reloading lead-shot but this will wear them out sooner.

MODEL "C/CS" INSTALLATION


Step1- Select a Mushroom-Shaped Insert first and insert it in the recess with hand pressure.
The flat surface of the Insert should be visible when installed. Place Bar upside down on flat
and hard surface, (preferably steel) and take a punch-tool and tap it repeatedly with the hammer
until the top of the Insert is flush with the top surface of the Shot valve. If the Zinc-Insert still
sticks out in a way that interferes with the movement of the Bar, remove excess material with a file.


Step2- Insert Plastic-Dowel-Pins and Setscrews into both end holes of Bar Body.


Step3- Slide the Universal Charge Bar into your shot-shell reloading machine; making sure that
the hole for the Philister-Head Screw is facing forward. When the Bar is in place, turn the
Philister-Head Screw all the way in. and push the Bar all the way to the left. (Use our Philister
head screw that comes with the Universal Charge Bar. The smaller head diameter of our Philister
head screw allows the Bar to travel further and therefore to drop the charges more efficiently).

 

MODEL "D/DS" INSTALLATION


1) -Select a Mushroom-Shaped Insert first and insert it in the recess with hand pressure. The flat
surface of the Insert should be visible when installed. Place Bar upside down on flat and hard surface,
(preferably steel) and take a punch-tool and tap it repeatedly with the hammer until the top of the
Insert is flush with the top surface of the Shot valve. If the Zinc-Insert still sticks out in a way that
interferes with the movement of the Bar, remove excess material with a file.
-Insert Plastic-Dowel-Pins and Setscrews into both end holes of Bar Body.


2) Take our Cam-Bracket that comes with the Universal Charge Bar and bolt it onto the D/DS Bar
as shown in Fig.2

.
3) Remove the MEC Standard Charge Bar and the original Roller-Cam from your progressive
reloading machine.

4) Slide the Universal Charge Bar into your shot-shell reloading machine; making sure that the
hole for the Philister-Head Screw is facing forward. When the Bar is in place, turn the Philister-Head
Screw all the way in. and push the Bar all the way to the left. (Use our Philister head screw that
comes with the Universal Charge Bar. The smaller head diameter of our Philister head screw allows
the Bar to travel further and therefore to drop the charges more efficiently).

5) Install our Roller-Cam in place of the original roller-cam. First hook it up to the pull-rod, and
then use the same bolt and nut, which was holding the original roller-cam to the machine.
(See Figure #2). All you need is a small adjustable wrench.


6) Turn our Spring-Retainer Screw all the way in on the left rear of the Bar and connect it with
the original spring.


7) Make sure that the Bar will travel the entire distance possible. If necessary, adjust nut at the
bottom of pull-rod. If the Bar is not going back to the right when reloading, lower the powder-drop
tube somewhat to activate the release of the Bar to the right.

 

UNINSTALL MUSHROOM-SHAPED INSERTS


- To remove a Zinc-Insert: Insert a punch tool in punch-out hole and punch out Insert with
the hammer (a nail will also work but is not recommended)
- To remove a Plastic-Insert: Apply finger pressure
Note:
The metal inserts are recommended for lead shot;
the plastic inserts are recommended for steel shot.

The Scales on the Adjustment Knobs


The circumference of the adjustment knobs is divided into 40 numbered increments. Starting
with 0,1,2,3 etc. up to 39 and back to 0
again because it will be the number of the next increment.

 

Scales on Bar Body.
These scales are marked in increments of 20 lines, numbered from 0 to 20 as shown in Figure 3.

Reading the Powder and Shot Chart:
Find the desired powder and weight on the chart and take a reading. Every reading consists
of two numbers. For example: For 48grs. of 571 powder the reading is 8 +13.
The first number, 8, stands for the scale setting on the bar body. The second number, 13, refers
to the numbers on the scale of the adjustment knob. The reading on the shot charge is handled
in the same way.

Adjusting the Powder and Shot Valves


The UNIVERSAL CHARGE BARS manufactured before February 1994, did NOT come with
Copper-plated-steel springs between the bar-body and the adjustment knobs. If yours is such a bar,
follow Step1 and Step 2a below.
The UNIVERSAL CHARGE BARS manufactured since February 1994 (starting with the warranty
number # 231751), come with Copper-plated steel springs, and located between the bar-body
and the adjustment knobs, easily visible. If yours is such a Bar, follow Step 1 and Step 2b below.


STEP 1:
To make a setting, first loosen the Setscrew near the adjustment knob.
For example, a reading of 8 + 13, first turn the adjustment knob CLOCKWISE until the Reference
line on the powder valve is somewhere between line 7 and line 8 on the scale of the bar body; then
keep turning the adjustment knob SLOWLY until this Reference line on the valve is in line with
line 8 on the scale of the bar body.


STEP 2a:
At this point, the O-line (# zero) on the adjustment knob is in line with the Reference point at
the end of the bar body. Keep turning the adjustment knob CLOCKWISE for the additional
number of increments until the Reference point indicates the number 13 on the scale of the
adjustment knob.


Note: On this type of Bar, accuracy is possible only if the Settings are arrived at by turning the
adjustment knobs CLOCKWISE. If you accidentally pass by the chosen setting, turn the knob
back and approach the setting again. This is because there will be some lost motion in the
adjustment knob when its direction is reversed.
When you are satisfied that you have the right setting, tighten the setscrew near the adjustment
knob with the Allen wrench supplied.

STEP 2b:
Keep turning the adjustment knob CLOCKWISE until you reach the 13th increment (on the scale
of the adjustment knob); next turn the knob well past the 13th increment first (to about the 18th increment);
then turn the knob COUNTER CLOCKWISE to return to the 13th increment.


Note: On this type of bar, accuracy is possible only if the final setting is arrived at by turning the
adjustment knob COUNTER CLOCKWISE.
When you are satisfied that you have the right setting, tighten the Setscrew near the adjustment knob
with the Allen wrench supplied. The Settings for the Shot-valve are done the same way as those
done on the Powder-valve.

How to make settings, which are not shown on the chart:


The powder chart shows values in full grain-increments only.
Suppose one needs a charge of 43.5 grs. instead of 43 grs. or 44 grs. of SR7625 powder.
The setting for 44 grs. of SR7625 is 14 + 30.
The setting for 43 grs of SR7625 is 14 + 13.
Subtract 13 from 30 = 17 increments.
Then divide 17 by 2, which is 8.5, and add the 8.5 to 14 + 13, which then becomes 14 + 21.5.
This setting will give you a nominal charge of 43.5 grs. of SR7625.
The same method can be applied to all other charges and settings.
For more info regarding different Settings, please visit our Web Site.


Please note:
Even though Figure 1 and Figure 2 are depicting the Model "D/DS", and Figure 3 is showing a part of Model "C/CS", the elements of adjusting the powder and shot valves are the same for all models. The Dowels and Setscrews must be inserted in proper sequence, as shown in Figure 2.
If a plastic dowel is lost, No 7 shot pellets can be used to substitute.
Most settings are either right on or will throw slightly smaller charges in order to provide a safety margin.
When using coarse powders at minimum settings, it is advised to remove the Brass Washer.

 

HOW TO CHECK POWDER CHARGES


Suggestion: Completely reload 25 rounds of shot shell. Then take ten rounds from somewhere in the
middle, cut them open and weigh the powder on a reliable scale. The weight difference amongst any of the ten charges should not exceed + or - 2%. On a charge weight of 20 grains the weight difference should be no more than 0.8 grains

GENERAL CARE


• Add grease to roller-cam from time to time for Model D/DS.
• Do not add oil or grease to any other part of the Universal Charge Bar.
• Do not disassemble the Bar; disassembly will void warranty.

CAUTION


-Use the powder and shot chart which came with the Universal Charge Bar ONLY. DO NOT use old
powder and shot charts which were issued for the old plastic Charge Bar (Model B201, manufactured
before 1981).
-The new zinc die-cast Universal Charge Bar model "C/CS" and "D/DS", or any other model “C”, “D”
Charge the method of calibration for these models are different entirely.
- Using the wrong powder and shot chart could result in serious damage and/or injury.
- DO NOT use the Universal Charge Bar without a POWDER SCALE.
Common sense precautions are advised. Make sure you fully understand the instructions before
beginning. If you do not clearly understand the instructions, DO NOT use the Bar. Avoid careless
handling of flammables and explosives as this can result in serious injury or death.
We endorse checking charges with a reliable scale and adhering to loads recommended by powder manufacturers. We also advise the use of safety glasses. We disclaim all responsibility or liability for
damage or injury resulting from reloading shot shell, etc..
