A while ago I stumbled onto a Ruger super blackhawk in .480 and an almost complete reloader's system (dies, powder, ammo, and some brass) at a more than fair price and I liked shooting it immediately.
The fly in the ointment for a reloader is and likely will be brass availability. So I ultimately found that Starline does and likely will continue supplying .475 Linebaugh brass and I got 500 which in addition to the few hundred native .480 brass I already have may keep me shooting for a long time. I just may get another 500 pieces of .475 which should be enough to last a lifetime
To cut cases I bought a Harbor freight 2" mini cutoff saw ($35) and genned up a method for cutting cases fast and safely to within max/min case length specs. Each case took about 45 seconds including deburring the ID and OD of the cut case.
