Re: Surplus Powders in 300 RUM?
I'm using 104 gr wc872 under a 190 hdy bt in my 300rum with rp brass and a 215. Groups just fine and cheaper to shoot than a lot of what's out there. I'm also using rl powders in a couple of loads, but wc872 does well with the 190. The kegs I got a couple of years ago were super close to aa8700; start at least 10% down though as mil-surp does vary from lot to lot.
