What would be the preferred carry weight for a 500 nitro double?
Min 10lbs at the absiolute minimum, pref 11lbs - 12 lbs but make
sure it is well balanced - ie not barrel heavy.

Any real world advantages over a 470 nitro?
Ye, a 500 Nitro hits with more authority than a 470 but if you shot
each animal in the correct place with either (but the same place for both,
they'd both die.

Once you go over .5", it does have an effect.
