... But I can't imagine not bringing the double - after years of perfecting accuracy in my rifles, and expectations of accuracy from myself and equipment, choosing the double for the sure and fast second shot but giving up that accuracy feels strange. Any thoughts on the dilemma?
If you can put shots on the double in a 4" group at 50 yards the double is accurate enough. You most likely will not be shooting an elephant any further than that, probably 15-20 yards.
