I got fed up with trimming/reaming 5.56mm NATO brass, so I broke weak and ordered a Frankford Arsenal Platinum case trim/chamfer/etc. station. It came in a few days ago. I set it up, and put in my first test case to the trimmer - it ran about 10 seconds and stopped turning. I thought that was odd. I backed the Case Holder assembly out a tiny bit and the motor started running again, BUT, the Locking ring was jammed tight, so tight I couldn't move it with hand or hand tools...so I called Frankford Arsenal. The customer service guy was very professional. He used the unit they had in the office and couldn't replicate the problems, said he'd never heard of that happening. I told him right up front it was probably my fault. Long story short - a new unit is on the way to me and my old one will be winging it's way back, no charge, no fuss, no muss. Kudos the Frankford Arsenal!
