M&M,
H&H, if you would be so kind as to comment on this Garrett article I'd appreciate it. I have read a lot of theory in my life, but their assertions seem counterintuitive unless there is another, undefined factor.
Here goes,
The major problem with this article is who sponored it. Garrett. They are guilty of some pretty outrageous propoganda concerening the .45-70. Just as Weatherby was guilty of pushing the velocity kills agenda in the past Garrett is the anti velocity agenda. Why? Because they are trying to sell .45-70 ammo that's why.
Quite simply the reason we haven't seen African hunters turning in their Nitro Expresses and .458Lotts by the droves to go buy .45-70's is that years of experience have taught us that a 500gr bullet producing about 5000Ftlbs of energy (that works out to around 2100-2200 fps) is just the right combination of penetration and striking force required to deal with thick skinned DG.
I have seen a 500gr solid from a .458lott hit a buffalo's pelvis smash it then proceed to penetrate all the way into the neck skin on a running away buff. A freind of mine shot did a frontal brain shot on a bull elephant with his .450 Rigby the bullet went through the bulls skull through the neck muscles and he found the bullet lodged in the skin above the bulls hind leg.Bopth of these circumstances prove that wet news paper may not be indicitive of true performance on real live animals.
I seriously doubt that a .45-70 at 1500fps can even closely compare after hitting some serious bone. Wet newspapers beware however as we have just discovered the newest hydrovolemicpapirus stopper.
The very hottest .45-70 loads generate about 3500FtLbs of energy. Which may or may not have any affect on during a charge situation if the animal isn't brained or spined. I'm not saying that the .45-70 doesn't penetrate well it does. While penetration is important there is more to it than just that. lets take that same scenario and add in the expanding bullet. In that case I think you'll find some drastic differences. Their is simply no comparison, the faster heavy rifles up to a point are far more effective. The magic point seems to decrease after about 2300 fps. Anything faster in the .458 500gr load tends to give eradic bullet path after penetration.
Vince Lupo who is Garretts .45-70 poster child went over and took the dangerous 7(elephant,buffalo, rhino, hippo, croc, leopard and lion) in one hunt with a .45-70. He claims that of the 7, 4 of them developed into a full charge situation........AHHHHhhhhh *****. Ezcuse me...... In anycase if that is the case, if he actually was forced to stop 4 frontal charges I'd say he was having some major problems with his chioce of gun, wouldn't you? Not to mention his PH must have done alot of running when he should have been shooting. Maybe his name was Wayne and he drove a Geo Metro and was an ankle braclet afficiando????
And last but not least least two weeks ago when my buddy Tim shot his big hog down in Texas my other buddy Ashley Emerson meet us on the ranch and he had just returned from a major no BS bullet penetration test that was not sponsered by any one manufacturer (imagine that) and he found that the cast core lead bullets were failing at an alarming rate after hitting something solid before going into a stack of wet newspaper. Almost like a gift from the hunting gods he was able to shoot a hog with his new Bowen built Blackhawk .44mag using 330gr Garrett Hammer heads. The hog died not doubt about it. But the bullet or i should say both halves of it were found in the skin of the off shoulder. The ole hammer head split in half on a little ole 200lb ferral hog. \
How do you feel about using cast core lead bullets on serious stuff?
I won't do it.
Give me a monlithic solid 500gr .475 or .458 at around 2150 or so and I'll be happy and feel comfortable because I know it works.
All of you in the .45-70 mafia are cleared to proceed as you like. I am just expressing MY opinons and my personal experiences.
Fell free to sherd them at will.
M&M sorry to rant on but you did ask me to....
