Good, but not good enough for the price they want for it lately. As far as the 300 wsm, you can use most of the normal mag powders, but you only have the same case capacity as the 300 h&h, so slower than rl22 or h4831 won't be at full pressure.
As to rl powders not being good at long range because of a supposed sacrilegious temp. sensitivity, all I can say is I've almost always got the best speed, accuracy, and uniformity with reloader. And it real world testing, the variance between high and low is usually less than hodgdon. Rl22 is all I shoot in my 300win browning a-bolt lh stainless stalker. I've got around 2 kegs just for that rifle.
