I have always used MEC Sizemasters for my single stage presses, but have also been intrigued with the Ponsness Warren 375C.

Has anyone ever used both?

Pros/Cons?

I've used a few MEC Marks and they don't hold a candle to the PW, though I haven't used the Sizemaster.

Better???If better means less expensive,does the job ,is simple to adjust,parts readily avaliable most anywhere and more users to ask questions should the need arise---MEC

Never used a Ponsness but have five MEC's. Looking forward to more comments from people that have used both!

I have sizemasters and PW 375C.
I like both reloaders.
My cons and pros between the two.
Sizemaster.
Pros
Collet resizer. Primer tray
Cons.
changing dies for different gauges.

P/W
Pros
Changing gauges.
Cons
No primer tray.
resizing- uses die-not as good as sizemaster resizing.

Also when ejecting shells from die on P/W.
If one wants to load a light load of shot, the P/W can push the crimp too deep.
as a shaft pushes on the shell to eject from die.

I have used both for years. I now own 5 PW's and no mec loaders. The finished product from the PW's is as good or better than factory ammo. The versatility is far superior to any other loader. For instance, I can load 16ga 2.75" shells and 16ga 2.5" shells, both with perfect crimps, on the same loader. I did have to buy a 16ga die and shorten it by.25" but that was easy. I also prep all my hulls with a mec supersizer before I load them, but that would get done any way. All my 375's cost me less than $100.00 ea.

I agree on the sizing issue with the PW dies- the shell is much easier to push out of the last/first station and so less pressure is put on the crimp.

I sold my Mec's now have two PW 375's. One 16/20 other 12/10. It's a good solution for me. Machines are pleasant to use easy pulls, less bench space too. No issues with the Mec's though good presses.

I have had both , sold the PW .

I like the Mec's for the pros that 3crosses stated and because it is just way easier for me .

I can get as good of crimps with them as any factory load .

I started on MEC and believe it was quicker than the 375 i got later. Quality of production is better but slower on the 375

I later blundered into a progressive PW in 16ga which can crank out the cheddite in bulk better than the 600Jr. But it is finicky to one hull type, wad, and load and once you get it adjusted to it, don't mess with it.

I tried MAGTECH brass and did not like them at all for smokeless.

I find that i have fallen in love with the RMC brass and I rarely load plastic these days.

If i were recommending to a starting reloader, it would always be the 600Jr with powder bushings, then once blooded to a universal bar. After a few years then consider moving onto to quality 375 if they really get into it.

Thanks guys!!!

I am a new convert to the 375c. I just listed my sizemaster for sale so I can purchase the tooling head for 16 and 28 ga.

I LOVE the 375! I feel like I am cheating on MEC, I have used their products forever.
