I don't think you have to worry about any supplies with the 6.8SPC.

If you want mags, check, PRI, C-Products, and Barrett, along with Bushmaster, DPMS, RRA, etc.

If you want brass, the SSA and Remington are available at $120 per 500, which is not bad.

The only thing that is lacking is a good, cheap plinking load, which SSA is taking care of that with their 100 Gr. FMJ ammo coming out. And they are also selling the bullets for reloading.
