Get Cabela's Shooting and Reloading catalog for 07'. The first 3-4 pages are just different types of ammo in bulk. I have the catalog in my hands so I'll post the prices right here:

.30-30 Winchester Ammo: Grain round-nose, flat point.
150 grains- 100 rounds...............$69.99
175 grains-100 rounds................$69.99
Both come with a dry storage box for free.
