There’s 480 brass available on GB and Starline makes it. It’s back ordered right now, just like every other supplier/manufacturer. Most of the cast bullet suppliers have offerings in .475. I don’t pollute my revolvers with jacketed bullets so I cannot speak to the availability of jacketed.
Making brass from 45-70 is certainly doable but a pain in the butt. That’s a lot of trimming. The rim size is larger on the 45-70 so might need to be turned.
I have a Ruger Bisley in 480. It has become my favorite big bore revolver.
If you’re going to own one it would behoove you to cast bullets for it. I like heavy cast bullets in mine. I never got the whole big bore, light bullet thing.
The 480 is a big hammer but a very shootable big hammer.
