Hello,
I have a new Mec 8567 re-loader. I'm having a problem with the primer seating post. It appears to be too short. It will not stay in place. Does the head on the primer seating post supposed to protrude up into the spring pad? For any one with experience these loaders I'd appreceiate any help.

Thanks,
p3ordie

It should protrude up into the slug looking piece (that the primer gets dropped into before seating) a little, but not much. There should be a small indent in the base that the bottom of the rod sets into, keeping the bottom located. If the bottom is not in the indent it will not stay in place.


Hope this helps, holler if it doesn't.

HSMITH,
Thanks, The seating post on mine does not protrude into the spring pad at all. I think it is at least .025"-.050" below it. The only thing that is holding it in place is tension from the spring. After I re-load about 10~15 shells it starts to work it self out of position. I do have the lower part of the seating post in the indent on the base of the re-loader. I'll have to call Mec when they open on 2 JAN.

The powder tube is also the 'ram' that seats the primer and it is adjustable(up and down) which increases and decreases the amount of spring tension that is applied- which does affect how much the seating post goes in - I believe. You may want to "lower" the ram a bit and see if that works. Lower a little at a time.
If that is the problem, I am a little surprised that your primers are fully seated and not causing some drag as you rotate the shell carrier.
But- I am no expert.
Good luck

The ram tube does not affect the static location of the rod in the plug, but it does afect primer seating depth as you mentioned.

If I follow the original poster correctly, the post is not protruding up into the primer plug at all, and with the motion of the press it eventually is "walking" out of position preventing operation.

Apparently, I didn't read the post properly. Disregard my advice as it won't help if the stem is too short.
Sorry about that!!

On my Grabber the priming post on the guide post is flush with the top of the spring pad (slug, plug ) when the spring is compressed. It's a little difficult to acccuately measure how far down the priming post is when the spring is relaxed, but it's nearly the thickness of the spring pad which is .375", 3/8". I'd say the guide post won't stay in place if it's .050" short. Mine is 3.130" long.

It's also possible that the base is out of spec, and the carrier plate is too high. Mine is 3 1/4", minus a couple of thou, above the bottom base, inside measurement.

Jack,
My primer post is .002" less than what yours is (3.128"). But I did measure the distance from the top of the base to the bottom of the carrier plate, mine is 3.285". If yours is 3.250" this could be the problem. I really do appreceiate the information! I'm calling Mec tomorrow, its sounds like I might have to send this one back
:banghead:

Thanks,

BTW, the flange on the spring plug is .180" thick and the plug sit a few thou above the carrier plate. If the flange is too thin, the priming post could lose contract, and the shells would jam a bit when you advance them.

That extra .035" clearance is likely the problem. Bottom line is, you shouldn't be able to swing the priming punch out of the hole in the pad when the bottom end is in the detent on the base.

I got my Grabber used and I had to call MEC to sort a few things out. The gent I talked to was quite helpful. You'll love it when you get rolling with that baby:D

Bye
Jack

Called Mec today. I explained the problem I was having and the tech knew right away what was wrong. I am not the first person to have a problem with the 8567. There were some made out of spec. The shell carrier was welded in the wrong place. They made a longer primer seating post to fix the problem. They are shipping the part to me today(no cost). I guess thats cheaper than replacing all the re-loaders out in the field.

Thanks,

You will find over the years of trying to wear out and tear up your MEC that they take pretty good care of you. I have always had good experiences dealing with them.
