I am thinking of either reloading or having a friend of mine to
load some 480 for my SRH and was wondering which dies
are the best to use?

I've had pretty good luck with my Hornady 4 die set. I've not loaded a ton of ammo on them but the price is right and they appear to be of good quality. These are carbide type dies that do not require case lubrication...be sure you make note of which sets are and are not when you purchase, as many of them are not.

RCBS also makes carbide dies for your 480 they run about 37.00-38.00$.

Hoeram :D
