I have an RCBS Junior from the early 80's -- I almost went with the Rock Chucker back then, but got a good deal on the Jr. The Rock Chucker is more robust and has always been a great single stage press. I only reloaded .38Spl/.357Mag & .44Mag back then though and the Junior was more than adequate. I still save my brass -- .38/.357, .44, .45 ACP and .308Win. ya never know, one of these days I may find a need...
