I had heard of the 6X47 but not the 6X45. Might be a nice round for a Contender. I also got a set of 7MMTCU dies. I am going to have to try that one out. Have a friend with a bbl for the Contender in that caliber. The 6X45 wasn't listed in my (somewhat) dated copy of Barnes Cartridges of the World>
