You made me remember reading Selous's accounting and how when in a herd, his BP failed to fire..he handed it to his tracker, who, not knowing it failed, loaded it again, and handed it back with a double charge--this time it went off and knocked him out with the gun exploding ..

AS to the .303, before I got really involved in African hunting I had no idea it was used that much in Africa for big game.. The very first centerfire rifle I ever bought was when I was 12 years old--I bought a army bolt .303---used if for the next 8 years shooting everything from Deer to coyotes..worked great.. Little did I know at the time I have an "elephant gun"
