Hey reloading gurus! Tell me what is causing this! I get one of these every 5 or 6 shells. These 28 gauge hulls are very finicky i am learning! I am using a MEC 600 JR. I converted it to 28 from 12 and the crimp is really giving me fits!

Please share ideas! I wasted 8 hulls out trying to load 25.

Call Mec and talk to them . They are very good about helping with problems with adjustments on their loaders .
Had the same problems with my Grabber when I first switched over to the AAHS hulls . Took a lot of very small adjustments to solve the problem . I still get a bad one every once in a while .
Those hulls may not be wasted . Shoot them and they may crimp fine the next time you load them .

i just adjusted the cam itself and load 10 that look a ton better than the early ones! If that doesn't work, I will call them!
