Chargemaster 1500 Speed Adjustment

1. Turn the unit on.
2. When 0.0gn is on the display, press BOTH the ENTER and the EDIT MEM keys on the dispenser at the same time. Hold for a second and then release. If done properly ADJUST PARAMETER should scroll across the display followed by HSP 00015.68 (This number represents the number of grains away from your entered charge when the tube will shift from fast speed to medium speed. That is at 15.68 gn from your target charge the dispenser will shift from fast to medium speed.) To speed up the unit, this number needs to be decreased and to slow down the unit, this number needs to be increased. (On a slow unit, I would change this number to11.00 gn this is done by pressing the following keys: 1 1 0 0 ENTER (pressing the enter key sets that value and moves to next setting in program in this case, to medium speed to slow speed setting)
3. HSP 00003.42 should scroll across the display now. This number represents where the unit will shift from medium to slow speed. Using the same process as before in # 2. For a slow unit I would change this number to 2.50 gn this is done by pressing the following keys: 2 5 0 ENTER (pressing the enter key sets that value and moves to next setting in program in this case, to slow speed to trickle speed setting)
4. HSP 00001.08 should now scroll across the screen. This number represents where the unit will shift from slow speed to trickle. Using the same process as before in # 2. For a slow unit I would change this number to .90 gn this is done by pressing the following keys: 9 0 ENTER
5. This is all the adjustment that needs to be done to the unit. You need to press the ENTER key to cycle through the rest of the program. (approx. 22 times) The unit will start its normal initial countdown process when this is done. You need to test out the dispenser now. Enter your target charge and dispense. I usually disregard the first charge. Throw a few charges at these settings to see if they will work for you. If they don’t, return to step # 2 and repeat the process. NOTE due to powder variations you may have to adjust the unit for each powder.

I haven't tried this on mine but looks like good reports on another web site.

I've tried tweaking these times and shaved a couple of seconds off a 45 grain dispense. If you really want to speed things up you can throw a charge circa 1 grain under and just let the CM do the final trickle.

I have read that speeding up foes cause accuracy problems with the CM. I've left mine as is as I usually prepare the case as it's being dispensed. I've never beaten it yet!

If you speed it up it is worth adding a smooth extension tube, a piece of aluminium turned to size works well and seems to stop that occasional 2/3 kernel dump at the end.

I gave this a try and it works brilliantly. I knocked the numbers down a little more than it said on the instructions and it is now completing the load before I can get the bullet seated on the previous case. Very easy to do and it does speed up the powder drop process. Give it a try guys you'll be amazed at how much faster it is.
