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

[jmort]

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

[mac60]

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.

[RickinTN]

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.

Let me fix this its a mec 650 its a progressive.

Thanks all

[trapper9260]

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.

[flyingmonkey35]

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

[Faret]

Let me know I have a older 650 also and could use the update too! :bigsmyl2:

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

[Faret]

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.

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.

[singleshot]

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

[Geezer in NH]

For best results with any sizer ring, lube the shotshell brass first.
I have loaded 100,000+ thousand a year for the last 40 yrs without lube and going fine with Mec 600 and a PW. Lube a shot shell bwahahahaha the mouth will be long gone before it would even start to make a difference.

[Boolit_Head]

The MEC sizer rings are carbide so no lube is needed.

[skeettx]

OK, OK, FELLAS
The MEC 650 PROGRESSIVE
press does NOT resize the hulls.
It does not have a resizing station
SOOOOO another method must be used, and the Lee, Lachmiller, RCBC, SuperSize will all work
and then the hull is entered into station 1 of the MEC 650 Progressive press

I to recently bought a MEC 650 knowing in advance in did not size but had seen the sizer option, it replaces the depriming pin and sizes and deprimes at the same time, ala MEC 600jr.

Not fond of that particular system having had a couple MEC Sizemaster over the years which use the "Power Ring" sizing system.

I found out my new 410 O/U is tight chambered and I do ned to size my 410's. I was visiting my local reloading store and he had a Super Sizer used for $50.00, got a little credit for the 20 Gauge set up and bought the 410 set up and screwed it in.

This is the way to go, I can do 500 case's in less than a half hour and not break a sweat doing it.

[John Boy]

But if anyone knows of a better way I'm all ears
I size & prime on a MEC SizeMaster then load on the MEC 650
The MEC 650 will do a half good resizing but not like the SizeMaster

[Firebricker]

John Boys idea would have worked for me if I would have bought my sizemaster before replacing my 650. Since I do my hunting loads on a sizemaster and all others on a progressive. The 650 is a decent press but all in all I feel you are better off going up to a model with the collet sizer on their progressives. Or buying the super sizer to go with it if you get a good deal on a 650. Reason being the super sizer is faster than if he uses the Lee but since he already owns the Lee not spending any more $ is good too. You could also probably get what you need to size on the 650 through Mec but it is a separate operation and it really did not work that great depending on the hulls and gun fired through. My 650 is long gone or I would post a photo of the sizing sleeve. FB

My vote is to 600 Jr. too. It's a Cheap and realiable unit that will make hundreds of rounds with ease. I've used mine for years without problems.

[mtgrs737]

Look for a MEC shot shell re-conditioner, it will de-prime the shell too. The supersizer is a fine machine but does not de-prime and costs more usually. They can be found from time to time on ebay and other places, or you could post a wanted on some of the shotgun forums.

I have four MEC 600's and I like them a lot, but for high usage a progressive is the way to go. MEC 650, Grabber, 9000GN are good machines at a reasonable price. You could just use another single stage press to resize.

[flyingmonkey35]

So for a update official word from MEC .yes I can add the function.




Neils,

I'm guessing you're going to hate this set-up for resizing. You will not be resizing as part of your reloading sequence and will have to half-dismantle your loader to do it. You will prob'ly choose to go back to your Lee for resizing rather than re-setup your loader each time you choose to resize. I have a 650 and do not resize with it. I resize on a 600 Jr. that I bought at a gunshow for $30. I do the volume reloading on the 650 and all other on the 600 Jr. Take a look at page 10 of the instructions for the 650 to see what I mean. https://www.mecshootingsports.com/Images/document/650.pdf Just FWIW. Regards, Woody

[Firebricker]

It will work but I did not like using very much. As Woody pointed out taking it on and off is more hassle than it seems unless you are not using the automatic primer feed. Some hulls were harder to eject from the ring and sleeve than others but it will work. So doing a batch of hulls on your Lee maybe a little faster. Your 650 will give you lots of good ammo whichever resizing route you take so let us know how it turns out. FB

[flyingmonkey35]

I think you are all right. I'd rather look for a used resizeer for 50 bucks later down the road

[W.R.Buchanan]

Flying Monkey: Aren't you currently sitting on my Coffee Table? My cats love you.

Do yourself a favor and look for a Lachmiller Sizer on Ebay. These things resize the base of the hull and knock the primer out. That way when you wash your hulls in a washing machine water doesn't get trapped in the hull.

Then you are starting with clean hulls to load in your 650. I do this to all my hulls and when you go to reload them it just goes much faster and smoother.

I used to just use the sizing/depriming station on my Pacific DL266 to do this operation, but then I got the Lachmiller tool and it is faster. I still do use the Pacific DL266 in .410 to do those hulls as there is no Lachmiller sizer made in .410.

Breaking down hulls and cleaning them prior to reloading just makes better looking ammo.

Randy

[Faret]

Always wondered how you wash them in the washer? A hungry mind wants to learn how!

[W.R.Buchanan]

You put them into a laundry bag or more properly two bags so they will balance out.. Then you put a bunch of tee shirts or towels in the washer to cushion the whole thing, add soap and let it run.

They come out pretty clean. Do size and deprime first or the primers will hold water and make a mess.

Once they are dry you are ready to start loading.

[seagiant]

Hi,
Randy, I've been around this planet literally 20-30 times. I've almost died 3 or 4 times between my work and my mis-adventures.Women, I'm not going to talk about,but one thing I'm going to do in the near future, is wash some shotgun hulls!

So I know, I have not missed anything while being on this planet!!!

[skeettx]

And when you wash your hulls please ensure they are compression formed hulls and a not paper wad base hulls.
Most Federal hulls are paper base wad except the Gold Medal Target hulls

[dakotashooter2]

Just a note of warning.. About a year back I ordered replacement sizing rigs in 410 and 20 ga from Mec. The ring for the 410 was shaving the head and leaving a ring at the bottom. It first I thought maybe my chamber was oversized and blowing out the brass. After some tinkering around I pulled the ring off the dies and tried to slip it over 2 brands of new unfired factory shells. Neither would pass through the ring. When I tried the 20 ga ring I had the same problem but not quite as bad. Both the original rings I had would go over the factory rounds.

[Duckiller]

My 40+ year old resizes hulls. It is a separate operation that is not part of the normal reloading sequence. From memory it is done at the deprimeing station. I loaded blue Magics and AA that I shot in 1100s. Never needed to resize.

[trapper9260]

I do not wash my hulls. I just brush them out when needed and make sure no dirt on them and then size and de prime them.
