Re: Load data for 300 win mag needed
It (wc872)is fair powder, but it is application specific. I've had it do very well and terribly poorly depending on the rifle.
The 7stw hates it, with 100 fps x and 4 inch groups.
The 270 and 300 u both like it, but with specailized loads; heavy bullets in the 300 u and heavy compression with bullets on the lands in the 270. If you have used h870 or 8700, this is pretty much the same game, but you've still got to start low and work it up as they aren't exactly the same. And if you aren't as over-bore as the 7stw or 300 u, you probably will be a couple of hundred fps down from top speed and burn a bit dirty. It is cheap, though, I ordered 2 kegs when it was still 50$ a keg. 40$ is even better.
