A different approach to the Chargemaster straw mod.
Works to reduce powder overthrows when using extruded powders like Varget and makes for uniform charge weights. The insert reduces the diameter of the discharge to from .310 to .245. Available in brass or aluminum, no difference in function between the two materials. $12.75 ea and $10.75 for each additional insert. Price includes shipping. Pm for details.

I've sold hundreds of these and guys love them.
*Measure your discharge tube]- If you have an older Chargemaster, it may have a smaller tube inside diameter in the .265 range. Make a note of this so I can spin one down to fit. 99% are in the .310+ range but its best to measure to be sure. The best way to measure is lock your calipers at .310 and see if they fit. If not, lock them at .308 and check, and so on. Find the smallest number that will fit and give me that. Another way to check is see if a .308 cal bullet will fit in the tube. All inserts are a few thousands undersized for a universal fit and you will add just a small piece of scotch tape or plumbers tape to the OD of the insert for a slip/snug fit in your discharge tube.
This insert also works in other electronic dispensers such as the Lyman and Hornady units.
The video is 43g Varget.
Now comes with additional small sleeve for even more accuracy for an extra $4. Slows it down a little bit is very accurate. You will want this little gem. It may all but eliminate overthrows entirely.
Here is a review of the insert with small sleeve from a guy on the Hide that has a nice scale...
"Poor man's prometheus. I picked up two of the new sleeve reducers from MDM12 and all I can say is wow. My current setup is 2 chargemasters and a fx120i with omega trickler. My first ten charges with new sleeves all within 0.02 of target charge. After 100 charges and checking against fx120i, I've only had to use trickler a couple times. I've yet to have one go over."

Anyone wanting an insert can PM me. Thanks.
Sorry, but I am not familiar with this forum (PM). I would like to buy two brass inserts and one small one. I can be reached at vd1brown@gmail.com. Please let me know how to pay. Thanks!

I just ordered via E-bay. Their estimated delivery USPS first class mail is Saturday Nov 12th.
I'm looking forward to receiving it and giving it a try. Hopefully it comes a little sooner.
Edit: I received notification today that a USPS Shipping label was created and is ready for the USPS to pick it up for shipment. I suspect I will receive it Wed 11//9 or Thursday 11/10.
That's pretty good considering I ordered it on Sat evening. Yea!

I'll be picking up my Chargemaster on Friday. Once I verify the tube ID, I'll be placing my order
Ended up ordering Chargemaster online. Should be here by the end of the week. As soon as it arrives I'll verify ID of tube and PM you with my order

PM sent. I want 2 of the Brass Reducers and 2 of the Aluminum Inserts (that further reduce the ID of the Brass Reducer). My tube measured .310"
Thanks
Thanks
Got mine this week, was a tight fit with no tape required. Did some test throws and seems to help. Might end up mess with the programming options to further tweak it.
