The last shot shell loader I had was a Texan FW back in the early to mid 70's. Penny and I were visiting a local pawn shop today and I found a MEC 600Jr in 12 gauge for $85. It's a later version with the nylon sizing (?) die instead of the steel die I was looking for. What should I look for on a used MEC600Jr. please? It had the paperwork and maybe 100 plastic wads with it in a random box. Am I right that it's a nylon sizing die? Should there be just one charge bar? Checking Ebay, the price seems about usual. Thoughts and guidance would be appreciated. Thank you. Don
