Hey guys. Been a while since I've delved into the 300 RUM. I was looking around for powder options and started looking at surplus powders. Are there any places with data for the 300 rum and these powders? Seems like the only thing available for powder out there in any quantity is the surplus stuff, and only the stuff for 50 BMG which works out well for me. Or even if there is a decent sheet with a comparison between surplus powders and commercial? Anyone loading this in their RUMs? Thanks in advance guys. Can't wait to get back out there with my rifle.
