50 Bmg load help

[Ruger007]

I have taken quite a long break from reloading my 50. Time to get back into it. If anyone has some good starting are known safe loads with the following supplies would be helpful.

Gun is a Noreen with a 32" barrel.


I have:
IVI brass
CCI primers 1000's
M33 bullets 647gr 500+
M17 Tracers

24lbs of WC872 powder
5lbs US869 Powder seems readily available too.
2lbs AA8700 powder
2lbs H870 powder. Which I would like to keep unless...

Mainly interested in the 872 as I have lots.

Thanks for your help.
