We all try to keep our powder as dry as possible by storing it in a container. You can now monitor the temperature and humidity in your powder tube while loading it to ensure you obtain the precise and accurate results you need. 

The NRA advises that powder humidity levels be between 55% and 65% for optimal repeatability in your ammunition. Since we could not readily find a product like this, we decided to design one. It’s a perfect way to add to the precision of loading with Dillon, AutoTrickler, and RCBS. 

The Dillon gauge comes in a matching blue color. The AutoTrickler gauge comes in a matching black color. The RCBS gauge comes in a matching green color. Each order comes with an extra battery.

• Custom sizes are available for any powder tube size. We only require a few dimensions from you, and we can then design, manufacture, and ship it to you in 1–2 days by mail.
