Resizing shotshells

[flyingmonkey35]

Hello all,

I just ordered me a used MEC 650

I noticed this press dose not resize the hull.

I've been using a Lee load all 2 for about a year now. And have always resized the hull.

The only one I can find is the mec one for 130 ish bucks.

I paid less for the press.

I can continue to use the Lee to just deprime and resize.

But if anyone knows of a better way I'm all ears

The Lee sizing ring is the lest $$$ and works.

The MEC 600 jr. does resize. It's not done with a collet, but with a sizing ring at the same station that does the depriming.

I've loaded thousands and maybe ten thousands of rounds on a 600 jr. I have used the rounds in several different shotguns and never a problem. I think you will be well pleased. As a tip, mine all (three of them) seem to prefer Remington STS hulls for a good crimp.

Yep, mec 600 juniors do resize using a size ring. The sizer rings do wear overtime and should be replaced occasionally with use.

All Mec have a resizen station on it ,it is the same one that have the deprime station.I have the Mark 5 one, 3 of them for 3 different ga. I also have a texans also 2 of them, but one is like the Lee Load all with the sizen die and the other one is like Mec.I do have a Lee load all also and a lee hand loader 2 of them also.You will get some loads out of the one you have ,It is a up grade from the load all for how i see it.

For best results with any sizer ring, lube the shotshell brass first.

So as a update the 650 dose not have the resizing feature.

I'm in communication with MEC and there may be a way to retrofit the resizing collet from a mec Jr.

I'm waiting to hear back.

[too many things]

you would be best to check feebay and get a super sizer you can use it on loaded shells {if you don't read the warning }
the problem with the ring is sometimes it will catch the head and crush the metal head as most don't have a brass head now

Let me know I have a older 650 also and could use the update too!

Check page 10 of this PDF seems a resize ring like from a 600jr will fit.

I wouldn't spend $100 on a MEC Super Sizer just yet. I had one. Sold it. Worked great, just never used it. I reload about 5,000 shotshells a year.
My progressive press (Hornady) gives me the option to size at a separate station, but I seldom do. Unsized shells fired in my gun and most range pick-ups work fine. but I shoot an over/under.

Sotshells fired in your gun probably will not need to be resized. The exception may be some semi-autos. Take the barrel off your gun and drop the fired hull into the chamber. If it fits easily, you may not need to resize. Especially check the range pick-ups that were not fired in your gun. If they don't drop in, size them on your Lee. You should only have to do that one time.

If you shoot a semi-auto that will not function with unsized shells that were fired in that gun, the MEC 650 may not be for you.

[flyingmonkey35]

I shoot both a o/u and a pump.

I've had bad luck not resizing the hulls. On my pump.


Never tried on my o/u.

I got the whole press with shipping for $140.

Mec tech wants a photo of it. To see if we can use the collet from the 600.

It "should work" and parts would be under $50

I think the shell carrier will be in the way. The newer ones come with the adapters that allow you to resize them in a separate operation before loading.

+1
Also gives me a chance to evaluate each hull--which I tend not to do it I go straight to the reloading machine

[skeettx]

The answer to your question: Yes you can use the Lee sizing system
Or a SuperSizer, or a Lachmiller, or a Texan or an RCBS, anything
to size before putting the hull in station 1.

Resizing depends largely on the size of the chamber the round was fired in and the size of the chamber in the next gun the round will be fired in. I can shoot hulls fired in my sbs in my pump but not the other way around.

[Firebricker]

I had an older 650 mine had a piece that you put in the shell holder and a sleeve with a resizing ring. You had to resize as a separate operation then take it off and load your resized hulls. With good hulls that have a real brass head instead of plated steel resizing was not usually necessary for my shotgun but not every gun would chamber them well. So I upgraded to a 9000g but continuing to use your Lee to resize will work fine and you already have it. FB
