Product Information

Proper resizing is important with today's close gun tolerances. We offer a radically new system. The shells we resize will work in the most exacting shotguns. The same system is built into all our NEW GENERATION of reloaders. The MEC Super-Sizer is different. It's better.

This Sizer is Super. The Perfect tool.

By Brian R. on Oct 03, 2020
OK, I just got it yesterday, good thing too. There were 3 in stock when I ordered this one and now they are all gone with none to be found anywhere. So you may be asking, "how can I write a review If I just got it yesterday"? I can write a review because this one completes the my four gauge set. I have had a 12 and 20 gauge sizers for since the 90's and picked up a 28 gauge a few years back. Between them I have collet sized thousands upon thousands of AA compression formed brass base hulls and the newer HS hulls. I load on Old Reddings, Mec with and without collet sizer's and I have four Ponsness Warren presses. I have never liked the mec sizer die for two reasons. (1) I believe it work hardens the brass. (2) The radius at the base of the ring keeps the ring from sizing the brass 100%. If you try to get that last little bit it is possible to compress the rim and effect headspace/rim thickness of the case head. With the collet die I can literally undersize the brass in comparison to the ID of the Ponsness Warren shell holders. This is where the payoff begins. With the pre-sized casehead the amount of force require to run the PW press is greatly reduced. Not just a little, but a lot!
I'm not a metallurgist but it is my believe the collet work hardens the casehead less than does ring sizing.
One other big advantage that comes into play is when there is a need to size steel case heads. I never have been, and never will be a fan of steel case heads, but if I have to size one I would much rather compress the case head with the collet versus ring sizing. To me steel on steel is always a bad idea and will eventually lead to tooling wear. If I had one knock on this particular sizer it would be the paint job. I gave it a 4 stars for this reason alone. All of my older MEC items have a nice even subdued coat of paint. This sizer looks as though it was painted with a shaker can. It is uneven and thick. Very poor workmanship, but in the end this is a tool that will get dirty while being pressed into hard service, and I have no doubt it will work just as well as the other three I have been using for years .

It is what it is...

I was a little hesitant about buying this. It is a lot of money for what it is. But it will allow you to reload and 410 Hull you ever cross. I have a mec junior in 2.5 and 3 inch and sometimes I run across a hull the collet sizer doesn’t like. If I had it to do over again I would have just bought a size master 410 loader. With this and the two junior I can reload any 410 shell I will ever need. It has one simple function and it is very good at what it does.
