I'm considering to sell my Merkel .470NE, which leaves me with only one DR in 9,3x74R...

Which countries allow 9,3 to be taken against elephant? Is it a sound choice?

I shoot a lot better with a scope, than with iron sights... To be honest, I've never made friends with the iron sights on the merkel..
I suppose I'd be better off using a scopeed 9,3mm all together?
