Has anyone ever used RL-22 for a 7mm RUM? I have see data for 25-06 up to 300 RUM with this powder and have never seen anything listed for a 7mm RUM. There must be some sort of starting load for this, right?
 
I know it doesn t answer your question
but I would suggest to try US869
if you haven t already
