Well, there's 7000 grs. of powder in a pound of powder and you'll use 215 grs per round. So figure 30 rounds per pound.
Primers run about $130 per 500, so a little over a quarter per primer.
Bullets, anywhere from .50-$2 depending on where you buy them from. And if buying surplus or match and in between.
Brass, .30-$2 depending on if you buy surplus once fired all the way to primed new. This cost goes away after first firing. If you keep your reloads mellow, you can get about 10 reloads on them.
