Weatherby 6.5RPM

A guy could use 6.5 PRC or 6.5-284 data and work up, as the RPM has more case capacity. 264 Win Mag data could be used too, start below max
 
Handloader magazine has an artical with load data for the 6.5 rpm. It was also on the weatherby website. The case capacity is around one grain of water less then the 264 win mag. You can use the starting load and work up. Reloader 25 works very well in mine with 143 eldx's
