What a slick little tool!
A friend handed me a box of "reloading stuff" yesterday - saying "Here - you might have a use for these things." Inside I found a .310 tool with dies for .45-70 and .45 colt, along with a SC set of blocks for the 454190 and a LEE .454 dia RB mould.
It was the first time I'd actually held a 310 tool. Soon I was "messing around" with it just to see how it worked. Now I'm entranced with the concept. Not sure what I'll DO with it - but it's a nifty little tool.
