Does anyone have experience working with WC872 in the 300 RUM? I will be loading Hornady 178 and 208 AMAX and 220 SMK. Any load data / direction is appreciated. I read that I could use AA8700 data.
Where does a fella get WC872? I have to use US-869 in a 270-300 RUM Improved.
I hear that 869 is a replacement for 870 and is possibly similar to 872, though I have no knowledge of this. I don't even know if 872 is a ball powder.
I can run up to 101 gr of 869 with a 180 270 cal bullet (Darn hot).
This should give somewhat of a guestimate starting point.
