I'm new to reloading and I finally bought this after getting 2 squids during a match. This has increased the quality control and my processes of my reloads. I am now more confident that I don't accidentally miss or under/over charge my cases.

Dont wait till you have a reload issue like I did to...

DAA Magnetic Powder Check 2.0 - it’s an awesome product, well designed and well made…..however as the new note indicates, it just doesn’t fit the Frankfort Arsenal X-10 press. The DA team was super helpful and Saul was awesome. We tried and after several emails with pictures back and forth,...

Not completely satisfied, i'm using 9mm brass with a fine spherical powder, everytime the brass ''sensor''-rod plumbs into the case there is a lot of powder splash. This on one hand makes the loads inconsistent and on the other hand i need to stop every 50 rounds to clean out my shell plate cause...

IMHO the electronic powder check is a must safety component when reloading on a progressive press. Even with the alarm, I also watch the magnet index into position at each press stroked as part of my loading cadence. This is an absolutely key tool to prevent squibs or overcharged loads.

This is a well build product. It has a wide range of sensitivity, meaning you can adjust it down to a few grams of gun powder or set it just about where you need an alarm. We purchased 3 of these units. We have them set for over charge condition. Our units alarm at .5 grams of over charge and do...

Important Note
The Dillon XL750 Powder Measure is angled such that the powder bar must extend directly over station #4 in the toolhead, and it cannot be repositioned. This Is not an issue if you have a short die in that station. However, if you wish to run a powder check in station #3, and a bullet dropper in station #4, as many do, this creates a serious problem. As a solution to this issue we are pleased to offer our  Extra-Short Dillon Powder Bar. (sold separately)

Frankfort Arsenal X-10 Note
This Powder check is not compatible with the Frankfort Arsenal X-10 press, due to interference with the Powder hopper activation arm.


The DAA Magnetic Powder Check 2.0 (US Pat. Pending) is a great addition to most progressive reloading machine, helping to ensure the quality and safety of your reloaded ammo.

The unique new design uses a high-tech Reed Sensor and a magnet assembled to the plunger Rod, to assess if the charge in the case is of the correct height.

In the new 2.0 design, the Sensitivity Adjustability feature has been removed, in favor of placing the Reed sensor in a fixed position on a custom built PCB board. That fixed position is one that sets the accepted height variance to about 2.0-2.5mm, which is what we found to be the best setting for all. More than sufficient to pick up a double-charge, debris in the case or a case without powder.
This design change now allows all components to be PCB mounted on the custom board – making the electronics much more reliable and long lasting.

An additional improvement to the DAA Magnetic Powder Check 2.0 is that the polymer shoe on the end of the plunger rod (which contacts the powder) has now been replaced with a brass CNC machined part, which helps to reduce the static electricity which could cause some powder to be lifted out of the case. 

The DAA Magnetic Powder Check 2.0 assembles onto a station immediately after your powder dropper, screwing into a standard die thread 7/8-14 station. However, unlike other powder check systems, the DAA product does not require a dedicated hole drilled through the tool head next to the station! It can be used on ANY progressive reloader which has an available station after the powder drop.

A powder-check does require the use of a station in your toolhead, so if you do not currently have an available station, you may need to combine your seating and crimping into one station using a 2-in-1 seat/crimp die to free up a station. These too are available from DAA.

The DAA Magnetic Powder Check 2.0 is activated off the top rim of the case rather than the base of the shell plate, this means that no alarm will sound if no case is present. The powder sensing plunger (now with brass shoe) enters into the case mouth to rest on top of the charge and measure its height, sounding an alarm if the  powder level is either too low or too high. It provides both an audible beep alarm as well as a bright red LED light when triggered.

The DAA Magnetic Powder Check 2.0 includes a replacement short plunger, suitable for use with rifle ammo. When using for rifle, simply replace the plunger, and assemble the steel rod upside down, using the end without the brass shoe to enter into the small case mouth. Parts included make this suitable to use with all pistol ammo (9mm and up) and for rifle from .223 and larger.

It’s compact size, slick and modern design, ease of setup and adjustability, make the DAA Magnetic Powder Check 2.0 the perfect accessory for your toolhead!
