MEC Issue

[J.B. Books]

My first thought is you need to adjust the depriming station and lengthen the deprime pin so it goes completely through the primer socket. However you said you have exerted so much pressure on some that you have distorted the bottom of the hulls, this suggests the primers are somehow fused to the hulls beyond their normal friction fit. How old are the hulls, did they get wet? Perhaps they were fired with excessive chamber pressure. Does this happen with any other type of hull? If not I am guessing the problem is the particular group of AA hulls you have and if so I would pitch them and start with some fresh clean ones. There is nothing inherently wrong with AA's for reloading, I prefer the old one's and I think the Remington STS/Nitro 27 is superior but you should not be having any problem depriming them under normal circumstances.

Are these hulls from AA's that you personally fired brand new and kept to reload or did you buy them from somebody else? What model MEC do you have and did you buy it new?

What Fred suggested will work on a hull on the bench if your only loading a few.It's a step that you shouldn't have to do. The reloader should do that properly for you. The problem is that if the primer is half out in the depriming station, you can't remove it from the reloader with that primer sticking partially down, there isn't enough clearance without bending something, probably the turret. What I do is cut the hull as close to the base as possible with a knife, then use something like a nail set or wooden dowl sharpened to a flat point and hammer the primer out. Problem with that is it drives the primer drop tube down into the fork below the base of the reloader. All in all, when this happens it's a real PITA.

You need to find the source of the problem and fix it. In my case reloading Top Guns and Estates I can look inside the hull and see evidence of rust before I put them in the reloader. I'm lazy and don't want to take the time to inspect hundreds of hulls while reloading. It's that 1 in a few hundreds that gets you.

Dave I have had this same problem, it's something in the collect fingers or at the bottom of the pocket. I removed the chain link and removed and cleaned and all is well. Good luck

Yes after I did this it statrted working....now to figure out the crimping proccess...
