DAA Reloading Magnetic Powder Check by Double Alpha
Dillon’s design of the XL750 means the powder measure charge bar extend out over station #4. If you plan to use a powder check in station #3 and a tall bullet dropper in station #4 – this creates an issue.
An available solution for this problem is the DAA Extra short charge bar.
The DAA Magnetic Powder Check (US Pat. Pending) is a great addition to any 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.
This original design also provides, for the first time, an adjustability option. By bringing the Reed Sensor closer or further from the magnet, you can determine how forgiving the powder checker will be, or how much of a range of variance in the powder level should be acceptable without sounding the alarm. At its most sensitive, the accepted height variance is about 2mm, which correlates to a powder error of less than +-0.5 grain. More than sufficient to pick up any of the mistakes we are checking for, such as a double-charge, debris in the case or a case without powder.
With the turn of a screw you can increase the acceptable range by distancing the sensor inside the electrical box, making the Powder Checker more forgiving and less likely to sound alarms you may not need.
The DAA Magnetic Powder Check 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 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 enters into the case mouth to rest on top of the charge and measure it’s 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 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 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 the perfect accessory for your toolhead!

I delayed buying this due to a handful of reviews saying it spills powder or didn’t return from a stroke of the press. After having an RCBS lockout fail on me , I went ahead and figured I’d give it a shot. WOW am I happy with thing !!!! I did start out by eliminating both issues I read about by shortening the rod travel with a cut straw and polished the rod before I even put it on the press. Set up is super easy and it functions flawlessly. Ran 1000 rounds the first night without a single issue and ZERO powder splash.

Purchased this to add powder sensor to my Dillon 1100. Easy to setup and the sensitivity adjustment is awesome.
Another Quality DAA product.

Just as good as the Dillon powder check with more sensitivity adjustment, built in LED with the standard audible alarm is nice to make sure you stop since the time is similar to the primer alarm. Easy to set up and reliable.
