<< First things first: When the guy attacking you has a doctor suturing up his hole, we'll talk. >>
First things first: I've never hunted elephant, I've only the information obtained from a few friends who are avid big bame hunters and who have the $25,000 (trophy fee + trophy prep + export + license + guide + travel + accomodations) to hunt elephant.
As for Bell, no source I know puts the total number of bagged elephants at "over 3000", though the difference between "over 1000" and "over 3000" isn't critical. Nor did Bell prefer the .303, his caliber of choice was the 7mm Mauser (7x57mm or .275 Rigby). He plugged a lot of elephants with the 6.5mm Mannlicher that Fraser had custom built for him. Not that the .303 wasn't widely used in Africa, but Bell preferred the 7mm over all others.
Bell's trademark was the brainshot, which he mastered by getting several natives to make a ruckus, distracting the agitated beast's attention while Bell manuevered to the animal's rear flank for a relatively safe side-rear brain shot. By all accounts Bell's record of instant kills was near 100% and I find no reason to believe Bell ever took a charging bull by choice.
No guide in Africa will allow their client to take a frontal brain shot with anything less than a .375H&H today. In many parts of Africa, it is FORBIDDEN to take dangerous game with anything less than a .375H&H.
Elephants are always taken at close range, preferrably between 20 and 40 yards. But, that doesn't mean unexpectedly 'happening upon' an elephant at 20 yards, which would be an incredibly dangerous situation. This is how numerous professional hunters, guides, and tourists have been killed.
You hunt elephant by using stealth to manuever within 20 - 40 yards for your shot, not by wandering aimlessly through the bush hoping to stumble upon an elephant at 20 yards. Someone doesn't know much about elephant hunting, and it doesn't appear to be me...
Precise shot placement is a luxury of hunting, which Bell was able to do with uncanny success because he was a master hunter who dictated the terms of engagement, not the elephant, luxuries that are rarely afforded when shooting to protect life and limb (stress fire) as when some 250lb felon burst through your back door and catches you in the middle of your late-night snack run.
Talk of 'pencil hole placement' is the exclusive province of those who have never been in a CQB gun fight of the type that is the pertinent topic in this thread. "Home defense" isn't tack-driving from your window at the neighbors acrosss the street. Home defense means CQB, the likelihood of a struggle, 10 feet MAX distance between the defender and intruder.
Not that practice shouldn't be a real priority for the home defender, or any gun owner for that matter, but talking of pencil holes through the heart simply won't be an option in most cases. If you can consistently put three of four rounds through a dinner plate sized target (critical chest mass) at 5 yards point-and-shoot (instinctive shooting), and are mentally prepared for the possibility that you may wind-up in a struggle with the intruder, you've all the skills required to make the best go of a home defense encounter, no matter the gun choice.
<< Don't tell me I'm not a real hunter or that I don't know what kills though. You criticize me for taking a dissimilar circumstance in hunting elephants, then you cite an emergency room. >>
I'll let your ignorance speak for you.
I cite an emergency room because you took the discussion off on a tangent about hunting animals with rifles. I brought it back to the topic, home defense against men, not deer or elephants. There is NOTHING about hunting animals with a 2700FPS rifle that is remotely applicable to home defense.
