I just carry my .470s in a nylon stretch belt that I made, that is sewed closed at the bottom and encases the whole round..They don't stick in nylon and come out easy without lifting the belt..the also don't leave a coat of vertigre on the case if left in the belt for long periods of time..I will take any big bore caliber from 375 on up to 600....works for me.

I'm not to hot on the finger carry in a tight spot, its a bunch of nonsense IMO...I want my hands free..
