It was horrible results with their ammo and their unwillingness to even discuss it with us when we contacted them as a safety concern.
We were getting reports from the field of sporadic results with Magtech ammo. So we bought a couple thousand rounds commercially to test it specifically. Out of concern for our own safety, we stopped shooting after a couple hundred rounds. We were having round barely move the carrier and dribbling brass out of th eport, and some that were so forceful that recoil was punishing and the brass was flying all over. Across a chronograph we were getting tremendous deviation (several hundred FPS0 from rounds within the same box iof ammo, with some reaching velocities far in excess of what any loading manual or computer program ascribed to max loads.
When we contacted Magtech, Initially they were very pleasant and expressed genuine concern, and some one was going to call us back. that never happened. We re-contacted them several times with our concerns and got no where. We investigated and found complaint after complain on line of similar issues from consumers, and similar stories of being put off by Magtech. With that and our inability to even express our concerns to them, we concluded that they weren't interested in our concerns and acted to minimize the potential danger to our customers.
