beware that if you are looking into getting a MEC 600 Jr. loader that the series from 1982 to 1985 are discontinued. you can still buy parts for them (mostly due to the vast quantities still in existance) but there are no new adaptations being made, such as primer trays and so on. meaning that you'll always be stuck loading the primers into the press one at a time by hand. I suggest the newer MEC 600 Jr. mk V. or... for $60 you can purchase a LeeLoad all 2. while not as stout as the MEC loader, I have loaded thousands of rounds with the LEE and it makes beautiful shells.
