I was on a B52 mission down in the Parrot's Beak one time that killed an elephant with a 750-lb. bomb. I remember thinking at the time that even Elmer Keith would have had to admit we were adaquately 'gunned'.
Elmer Keith was the father of the .44 Magnum, as you no doubt know. I was all of fifteen at the time (1955) but remember the big deal made of the gun and cartridge. Actually, I became interested in big-bore revolvers through the .44 Magnum, bought the first one I could find. I got the "Keith" bullet mould and started casting his semi-wad cutter plain-base 250 grain bullet.
The .44 Magnum is no longer the most powerful production handgun ctg. but it's very accurate and works great for pretty much anything one wants to hunt in N. America. Load it down in power just slightly and the gun becomes almost tame.
Well, enough about Elmer Keith. This thread is on the .50 cal. Don't own one but would like to.
