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 easy to set and reliable. I installed mine on a Hornady AP had to modify by shorting a couple threads.

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.
