"Just go`s to show that the lack of a super quick follow up shot with the .600 would spell the death of you in a 'missed first shot' situation in close quarters charging!"

Gryphon , I think that is true in some ways , some shooters get back on target faster than others , I like big bores myself , but admit 450/400 level you can stay dead on , 500NE & up it gets harder at my weight level (85Kg) , but if you hit em with a 500NE up , may well not need that shot LoL !

My 577's left barrel look's almost unfired !
