I think you need to specify what you're hanging. If it's meant to be hung and it's that heavy, it should come with instructions. If it doesn't, it probably shouldn't be hung.

Realistically it would be around 350lb but I am calculating 500lb as a safety margin. Instructions say to hang it to just one joist. I am being more conservative and planning to fix to a 4x4/2x4 over several joists to spread the load.

You aren't "calculating". You are "guessing". There IS a calculation you can make which determines what the effective maximum load of a swinging weight is.

I would spend a little time looking this up, or maybe pay an engineer 50 bucks for an hour of math.
