Mec setup problem

[Old farrier]

Hi chaps.

 

Been Reloding a few 10 bore Cartriges

2.7/8

Mec loader with short kit fitted absolutely fine powder drop wad seating shot drop new primed cases

 

Now here's my problem 😟

Once fired cases factory and home loaded cheddite red and Remington green

Remove old primer stage 1 this seems to dome the head and open out the rim

 

So what am I missing / doing wrong

 

All ideas gratefully received

I try and do some pictures

 

Many thanks

Not sure it's a block come crimpy thing that sort of grabs the case it's on a cam arrangement not sure if it's adjustable or wrong or if I'm just being a idiot

 

Thanks for your thoughts

Are you sizing on a collet sizer or using the basic ring type mec sizer? your running a spaniosh side by side im guessing they can have biggish chambers compared to american guns in some instances. Ring sizer and a spaniard could be an understandabe reason for your problem, post up a picture of the sizer your using.

Collet sizer .. Should be less chance of a problem to a ring. Yep lets see some more pictures. Bang goes my swelled case theory with a collet sizer.

What would you like pictures of ? 🤔

Get a used case de prime size it then do the same with a new case, then lets see it there is a difference, and wile your at it measure the case head diameters not so much the rims but the head sides on both the chedites and the remys. Are these cases brand new or once fired or some you picked up bought or was given.

Sorry if its 20 quesstions here but just trying to esstablish a few facts, see if anything surfaces.

Could be the deprime rod is set up or wrong some how.

Brand new from clay game

Only thing I can think is ? Is there a adjustment on it as I've put a Kit on it to turn it from 3..1/2. To. 2...7/8 and it's the only bit I never altered

New Colet. Also back it off a tad to extend its life.

Back it off a tad ax it's new.

Is that shorten the distance so it doesn't travel so far or extend it so it travels further?

Sorry if imbeing a bit thick 🤔

Is there a nut under the machine if there is you may need to slacken it off and adjust the resizer. Put a new case in it and adjust it so it just nips the new case that way it should put your old cases back to the correct size.

Set the sizer to size the cases to 0.800 to 0.805 you can slacken it off once you sort out the problem to the nominal sizes of your guns by example to the size of the tightest of them in the chamber, im suspecting that will be the 2 .7 8th chambered gun .

Is the primer rod too far out. ?

[Guest cookoff013]

Is a 10gauge not 860 thou?

Is there a metal ring missing from inside the bottom of the sizer?

I was reading this trying to remember how I fixed the same problem on mine ..... it was this missing part as suggested.

There's no metal ring in the sizer anyone got a picture of what it should look like or a part number

Could be the problem

I used to get that on my 9000 when the hull did not go all the way into the re sizer. It tends to be dirt or a small bit of shot gets stuck in there and prevents the base of the cart facing up against the collet bottom! This is indicative of the depth of the lip on the cart base! It's far too high, meaning it's not right at the bottom of the re sizer!

If it is the part that is missing, I had the same issue. This cost me a few geese on the marsh. My Xtrema wasn't allowing the cartridge fully "home", because they weren't resized correctly. This means the firing pin won't engage.

I found out what was wrong one day when I was cleaning my Mecs. I noticed that my 10 gauge Mec had the ring and the 12 didn't. I looked in my box and found said item. Problem solved.
