Metplate, Velocity, Penetration, Bullet Weight or Shot Placement?
If one ponders over the above question long enough your eyes may begin to cross over one another perhaps.
However, I believe back when factory bullets weren't able to keep up with the velocity of todays times, bullet failure was indeed going to take place. Thus the idea and testing seemed to sort that bit of information out for us. I don't think the boys in Africa should be given all the credit for such a finding. I myself believe that no matter how big a bullet might be or how slow it is going, the one thing it must do to down an animal is to penetrate it's vitals. I to this day believe that is above ALL things the most important issue.
Elmer Kieth did have a handhold on this idea himself years back no doubt! Today we do have bullets that can take the higher velocity of today's big magnums. Only to have the "Super Mags" enter the picture, which brings about more demise to the standard bullets, that hunters want to use on big game. Thus the bullet wars between companies has emerged, to the tune of who's bullet can travel the fastest?
Who's bullet is the best on penetration? Who's bullet is the most accurate at these "super sonic speeds"?
I don't think one has to Sloooow down a bullet, for the sake of doing a better job of killing a big game animal! I think what is most important is for the hunter to do his or her homework and select the bullet that will mushroom out, penetrate deeply and by all means, stay together (retaining at least 70% to 80% of it's original bullet weight) under the velocities they plan on shooting it from their gun.
I also think that plan Jane factory bullets are OK in some areas! Not for taking of elk, moose and mule deer being shot out of magnum rifles or Ultra magnum rifles at higher velocities. A hunter must use a little common sense these days in ammo selection, if not a reloader. Factory bullets today are far superior to those of yesteryear, so that should make it easy pickens for those who haven't learned the pro's and con's of bullet selection.
The other thing I wish to mention is that I myself have been doing bullet testing for over 20 years! I just don't trust everything you read in a magazine about this or that new bullet. I want to be "showed" how this product is going to preform in the hardwoods or mountain ranges. The best insurance one can take on a hunting trip, is to purchase the very best bullet available for your gun.
