300 wm powder identity question

[briang7511]

Since there has been no 300 wm brass available I ordered some federal 150gr speer hot cor factory ammo just to use the brass. I will reuse the 30 cal bullets in the .308, but I am wondering what powder is inside. I pulled one and it measured 72 gr. The box lists the velocity at 3150 fps.

If anyone might know what powder is inside I might be able to reuse it.

Factory ammo uses a unique blend of powder. But since it came with the 150 grain bullet. I'm sure you could use a similar 150 grain bullet. But I'd wait for a more experienced reloader to chime in as i could be mistaken.
