I am building a 25 Pronghorn /300wsm. There really is not much data on the different powders, i.e. RL 17, Imr 4007ssc, imr 4350, etc. If you have and would like to share data, I would appreciate all the help I can get. I will be using 75 gr up to 120 gr. bullets, federal large rifle primers.
Thanks,
