Mikemiller69gs Posted January 8, 2021 Share Posted January 8, 2021 This is my first foray into reloading and i'm learning as I go, so be gentle. I'm reloading 9mm with 147 gr bullets and using Winchester Autocomp. It calls for a charge between 3.6 and 4.0. I've made 50 so far one at a time and weighed 25 of them and they were all at 3.9 but two (3.8 and 4.0). I'm using the smallest distribution disk (.30) but I would have liked to have been at the lower end of the range. Am I at any risk at 3.9 and how do I reduce the charge if i'm using the smallest disk/hole. Thanks for any help you can give. Mike Link to comment Share on other sites More sharing options...
mscott Posted January 8, 2021 Share Posted January 8, 2021 You can either buy the adjustable charge bar or use something like nail polish to build up the inside of the hole to reduce volume. I hate to give advice not knowing how it works in your gun but you may be just fine without changing anything. A trip to the chrono would be a good idea.

Mikemiller69gs Posted January 8, 2021 Author Share Posted January 8, 2021 I'm going to run a few through my CZ SP01 (Cajun Production Kit) and see what happens. Thanks for the suggestions Link to comment Share on other sites More sharing options...
AzDanMan Posted January 8, 2021 Share Posted January 8, 2021 There is a modification that some are doing. It involves to drill and tap a set screw in the disk at the outside of the hole. Then you can screw the set screw in to lower the volume. Link to comment Share on other sites More sharing options...
Mikemiller69gs Posted January 9, 2021 Author Share Posted January 9, 2021 I shot a few through my Walther and my CZ today and all went well! Link to comment Share on other sites More sharing options...
Farmer Posted January 9, 2021 Share Posted January 9, 2021 I’ve taken electrical tape and put small sections inside the hole to reduce the volume. Usually a piece the height of the hole and half way around will reduce about .1 with some powders. The adjustable charge bar can sometimes be worse with lighter charges because the chamber doesn’t go back under the wiper as far as the disks. Make sure your getting a full throw on your disks and your not adding any extra vibrations. Link to comment Share on other sites More sharing options...
DRock Posted January 9, 2021 Share Posted January 9, 2021 I did the mod that AzDanMan mentioned and it works well, better than the charge bar did for me. That's a scratch not a crack next to the screw, but do be careful when you drill. I just have a hand drill. You can also get a 3D printed, after market micro charge from Titan Reloading for around $30. https://www.titanreloading.com/titan-reloading-products/titan-micro-charge Time is one thing, but once you start spending money on the Auto Disk, you might want to consider an Auto Drum. I have both now and use the Auto Drum most often. Dave Link to comment Share on other sites More sharing options...
