Can't find a Mec 600 Jr 410 ga 3 inch reloader
 

I've looked just about everywhere and no one seems to have a Mec 600 Jr 3 inch 410 ga reloader. What gives? Deman exceeding supply or does Mec just not produce many? I'm baffled

About 8 months ago I bought their last 410 650. They don't make the 650 anymore, or so I'm told. It goes just fine with my 12 and 20ga 650s. I had a 410 JR but like a fool sold it when I bought the 650. I would think they still make the 410 Jr, but who knows now a days.

May be easier to find a used 600 Jr. on Craigs list and buy the conversion kit. That's what I did.

Just bought a Sizemaster 410 from Midsouth Shooters Supply. Bit the bullet

I have a Parker repro,
A Browning, a Baretta .410
The Baretta chamber
Opening is tight and you need the sizmaster collet to resize the brass
Buy only Winchester .410 shells,
You will be glad

There are several on ebay right now. 600Jr, and Sizemaster

I'm not sure but I think the conversion kit is to go to shorter shells, like 2 3/4 to 2 1/2. You can just change what holes you're using in the main shaft to lengthen it for longer shells. So go head and buy one for 2 1/2" and do a 5 minute change to go to 3" 410s.
