Tune and Tweak Your ChargeMaster for Better Performance
Do you own an RCBS electronic powder dispenser? If you do, take the time to watch this ChargeMaster Tuning video from 8541 Tactical. This nine-minute video demonstrates how to re-program your Chargemaster to “tune” the dispensing process. The video shows the exact programming procedures to follow, step-by-step. Some folks want a faster powder flow — others tune their machines for a more reliable drop (with fewer over-runs). One cheap and popular modification is to insert a 1″-long section of a McDonald’s straw in the ChargeMaster’s silver dispensing tube. This works surprisingly well to smooth kernel drop and prevent “clumping” that can cause an over-charge. The McDonald’s straw MOD is demonstrated in this video, starting at the 6:22 mark.
Large-Diameter Dispensing Tube Mod
Many folks have had success with the McDonald’s straw modification demonstrated in the above video. However, some folks would like to get even better flow performance (with virtually no clumping). Forum Member Frank B. has come up with a new option using a brass hose fitting with a large outside diameter. The hose fitting (with tape wrapped around the barbed nose section) is placed inside the RCBS dispensing tube (be sure to have some kind of wrap — you don’t want metal-on-metal). Here’s how the unit looks installed:
Frank tells us: “I have found a cure for the over-throw problem. It is a simple 1/4″ barbed hose nipple. I wrapped a couple layers of tape around the barbed end for a snug fit. With this in place, I have thrown 100+ charges of Varget without a single overthrow. The ID of the barbed end needs to be approximately 3/16″ to feed a steady flow. This works because of the larger ID at the drop.”
Frank adds: “You can see in the photo that the powder is not stacking up. You can watch it drop one grain at a time. Hope this will take the aggravation out of your case charging.” For best performance with this brass fitting MOD, we recommend de-burring and smoothing out the front edge of the brass fitting over which the kernels drop.

The clumping has always been an issue for these rotational spout and honestly, anything that works will be awesome.
Thanks for the TIP!!!
This one looks a tad better and works a treat….

I use a piece a business card rolled while turning the spring action open up the channel letting more powder come out and on the slow down, it springs tighter and reduce the flow.Resulting in a reasonable time for dispense and no more over charge. After a while the rolled card gets coated with powder and gives even better result.
Not all of the dispensing tubes are the same diameter. I ended up cutting off the base of a .357 magnum cartridge and slid it over the outside of the tube. Works great!
I couldn’t find a straw that would fit mine. I’ve had it for a long time, so it might be different than the newer ones.
