Shotshell reloading

[skeet]

[QUOTE=Gil Martin;336571]
I have several MEC 600 presses and they work well when teamed up with a MEC SuperSizer. The MEC 600 press will resize the brass and the MEC SuperSizer resizes the rim. I have a few shotguns that will not accept oversize rims in the magazine tube.

I should have addressed this in my first post..As Gil says the thickening of the rim can and will happen. The cause of it with a 600 is when we use the regular shotshell sizer we have a tendency to try to size too far down and it squeezes the rim out and makes it larger..eventually it will no longer fit in the mag tubes of many shotguns..may not even fit the chamber of some guns. When it happened with me I just pitched the shell. Usually 3 0r more times loaded... And Gil is also correct..the Sizemaster is a very good loader(I have 4)..but unless you can find one under a hundred bucks or even less..stick with a 600 for a starter press JMHO...
