You don't get a second cylinder with the BFR and there's really no need. I think the dies are okay. I have gotten many -- no, make that MANY reloadings on the same brass and my load goes 1,350 with a 420 grain bullet. You will love your BFR! It is the best bang or the buck out there, bar none and the .475 loaded properly is a killin' machine! I have yet to shoot one that wan't accurate.

As wapitirod said, once you start shooting the .475s you probably won't mess with the .480 loads any more -- unless you don't like the recoil, but you don't really need to push the .475 hard for it to work.

Congratulations!
