I'd do one round and see if I could catch a glimpse of where the bullet is supposed to be.
id do a single round
a million is more than enough and I think a 5/6 chance of not dying is pretty good
How many empty rounds will there be? 5? If so I'd do it 5 times. Either I die or get 5 million. win-win.
I'd just take the bullet out and win ALL THE MONEY.
Just get one that's not in the middle of the city...
