This powder check is amazingly effective. We run an ammo manufacturing shop running 2000 rounds per day. Thank you Double Alpha for this great product.

Purchased two of these items, works GREAT, on first run had a media pin stuck in primer hole, the new powder checker caught the problem. Takes a little bit to get set up, but once set runs flawless . Will purchase again for my other presses.

Would have been five stars except if you live in a dry climate the plastic tip causes static cling and powder comes out of the case and than drops. You can used the other end but than it is a small tip area and seems to push into the powder. Should have made the tip out of brass to get rid of...

Easier to setup than the Dillon powder check. Really light the bright red LED with the audio alarm. No false alarms if no brass case at the powder check station. Cost less then the Dillon too.

I received the Magnetic Powder Check die and it is well made. I tested it on a single stage press and it works fine. I am sure it will be great on my Mark Seven Apex 10 when I receive the press.

Great product, works flawlessly. I have a Dillon XL1100 with the Dillon powder check, not happy with it. The Double Alpha unit is far superior.

I'm using mine on a Dillon 650 for 300 blackout and no powder spillage at all. I also converted mine to a direct plug in power source so never have to worry about a battery. It uses a 6VDC and 11A battery and found a 6VDC and 10A power supply on Amazon.

DAA Magnetic Powder Check
Die optimale Lösung für die sichere Munitionsherstellung, kein zu wenig, kein zu viel Pulver in der Hülse!! Einfache Handhabung und sicher!!

Compared to the Dillon Power Check the DAA Magnetic Powder Check was a breeze to calibrate. I like the DAA so much I've sold my Dillon PC and plan on purchasing three more DAA for each of my other tool heads. The bright red LED addition to the audio alarm is a plus.

This is a great idea, very easy to set up. I believe they are 'almost' there, but not quite. The problem is the plunger (I have only tested the pistol plunger) has a tendency to catch on the push rod. It binds as the rod is raised, so even if there is no shell in the holder, it lifts the plunger...

I have been waiting for this product to become available for some time. After receiving it and installing it(which was super easy) all I can say, is AWESOME. I will be purchasing another one for my 223 XL750 head. Do NOT purchase a Dillon powder check, get this one.

I will start off by saying mine arrived broken. The tab that holds the sensor head was broken and the battery was dead. I called and was sent a replacement in under a week. Great customer service.

My own observations the lock tab for the sensor head is a bit delicate. If you are aware of that...

Does a good job checking for no-powder or double charges. The boot kicks up powder when it makes contact with the case and ends up making a huge mess on the shellplate, really makes me wonder what powder they used to test this with before going to market.

DAA Magnetic Powder Check

(74)
Manufacturers: Double-Alpha Academy
DILLON XL750 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.

Description:

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!

Summary of features and advantages:

  • Can be used on all toolheads, does not require a dedicated hole near station.
  • Assembles onto any 7/8-14 station
  • Provides both an audible AND a visual alarms
  • Can be adjusted for sensitivity, to avoid false alarms
  • Includes all parts for both rifle and pistol use
  • Activates off the rim of the case, so no alarm sound when no brass is present
  • Slim and compact design.
  • Quality materials. Stainless Steel Rod, with aluminum red anodized die body. Rubber coated glass-fiber reinforced nylon for electronic housing

You can used the other end but than it is a small tip area and seems to push into the powder. Should have made the tip out of brass to get rid of this issue (wish you would offer the tip as as a after market part you can buy and replace the plastic tip). You can try to used static guard and spray the tip or dryer sheets but neither one work for me.

The problem is the plunger (I have only tested the pistol plunger) has a tendency to catch on the push rod. It binds as the rod is raised, so even if there is no shell in the holder, it lifts the plunger to make contact with the switch and gives a false reading. It is random, doesnt happen every time. I think they need to make the guide hole in the plunger 1-2mm larger.

[DAA Reply]: Yes, a powder check is designed to check for double charges or no charge. It is not designed for anything else. The foot of the rod does make contact with the powder, like other such devices on the market, and as it lifts out it may indeed cause a spill of a tiny amount of powder. In our testing (N350 and N310) it was a negligible amount. But I do believe it does depend on static electricity,. Which may vary from place to place.

Set this up on a Hornady LNL Progressive press with 9mm shell plate , Red Anodized threaded fitting wouldn't go down far enough to allow casing to lift internal plastic bushing to activate the micro switch , hit the top of shell plate ! Had to put in lathe and turn down the threaded area like EVERY die manufactured to put a step in it aprox. 3/16" to allow it to fit properly & actually work . Besides that , works like a champ
