.470 light loads

[Gareth flanged]

Hi

I'd like to use my .470 in the indoor range. I'd need a light loads with a soft lead bullet about 700 ftlbs.
Does anyone have experience of such a thing?
I'm wary of the case powder capacity.

My experience is you would be exceeding any indoor range caliber constraints with a 470. Second you must be a reloader to do what you are attempting. If so your filler would take care of any capacity issues
