Is the Chargemaster 1500 adjustable on speed?

I have a RCBS chargemaster 1500 scale/dispenser that I love to death.

The problem I have is that when loading accurate #5 (fine and light powder) at 3.7 grains it spits our about 4 grains every time before it stops and of course that won't cut it.

I have tried to email customer support but with no response.

Is there a way to slow this thing down if you want to?

Thanks.

Thanks mrawesome22. I have those. Where does it say you can slow the initial dispense rate?

Didn't read it.

If it is not in the inscructions, I would have to guess it is not adjustable.

Just a fyi, the Hornady auto charge has 3 speed settings for this very situation. The "when to start tricking" range is adjustable also. Great product.

Yes, this explains how to speed it up, but you can lower the values to slow it down I'm sure, I used this to speed my rate a bit.

^^^ That site was the one that showed me how.^^^

Tweaking the settings really do help speed it up without sacrificing accuracy. Just got one of these a couple of weeks ago and they are one slick unit.

RCBS finally got back to me with the instructions...

RCBS finally got back to me with the instructions to speed up or slow down the rate of powder flow. Not for the faint of heart, other than instruction 1.


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. If you have any questions about this matter please call our customer service line 800-533-5000 my name is Don Legg and I am more than happy to answer any questions you may have.

Do you have a piece of McDonalds straw glued in the tube?
