The DAA Powder-Spill-Prevention (PSP) Brush is a simple yet efficient reloading accessory that solves a real issue: How to prevent small amounts of powder being spilled out of the case, as the tool head of the progressive reloading press indexes? This problem is even more acute for reloaders using Autodrive systems on their Dillon machines, in which case you cannot use your hand to stabilize the case, as the shell plate indexes forward. Especially when reloading very full cases, powder spill can have a real influence on the accuracy of the ammo you are producing, and the accumulating powder on your shell plate can prevent the smooth function of your press, and require frequent cleaning. Introducing the DAA PSP brush solution. Just click this part onto your Dillon 1050 machineor to the Dillon 650 machine/Dillon 750 machine, and immediately your powder spill issues will be greatly reduced or completely eliminated. You’ll be able to index your shell plate faster, and produce more consistent, accurate ammo, while keeping your shell-plate clean and powder free.
