Unfortunately this particular caliber is about as controversial as talking religion vs evolution.
I'm not saying it can't be done, but if you do a search on cast 6.5x55 you will quickly see several threads which start off as simply this one has, but morph into something way out of proportion.
I myself have one I plan to cast for, but I have plenty of other stuff ahead of it on the list. Once I get there I am planning on having the time to spend to do it right and not simply pull up data and try different loads hoping to hit something.
