mono vs lead for Cape Buffalo?

[Puddle]

South Africa
Legal requirements in most Southern African countries stipulate a minimum of 375 for all dangerous game. A 375 or larger is recommended for Buffalo or Lion, while hunting Hippo, Elephant, or White Rhino may necessitate a caliber larger than 375.

In RSA a .375 on gubmint land. On private land? No so much...

I've yet to bump into a PH that didn't like a quality bullet out of a 9.3mm on buff.

And one last question: Stopping a charge straight head on within feet. Are you aiming for the head, neck or is it so fast and intense it's spray and pray and hit whatever you can? Is a solid or Barnes TSX best for a head on charge?

That thing will come at a speed where you will be challenged to aim and place a proper shot. If you have not spotted the beast and are in thick cover a charge from less than 10 feet is extremely dangerous. In this situation a debate between soft and solid becomes inconsequential.

What my PH tells me and this is interesting... is when an injured bull heads into thick cover, safety over anything else takes priority. Many outfitters now use a drone to spot the bull's position for the final kill.

It seems that some fragmenting lead and energy dump inside the buffalo leads to quicker kills over the mono-mentals and solids? Plus, less chance of over penetrating? Seems to be a plus.

I was surprised to read people use the Trophy Bonded Bear Claw TBBC on buffalo and it's success. Another bullet that could be a great buffalo round is the Federal Trophy Bonded Tip (TBT) is a thick base bonded lead core design like the TBBC but with a plastic tip and a bit more streamlined design.

I know moose are not buffalo but, from my own hunting experience in Alaska with the 300 RUM using the Berger's they have a much greater effect on moose after they're hit with that compared to the Barnes TSX. The Berger fragments and dumps it's energy inside the animal leading to a quicker kill. The moose reacts differently to Berger's as if it's been shocked and then it's legs buckle. I've never had a moose run off after being hit with a Berger but, they have run over 100 yards after being hit with the Barnes TSX on many occasions.

There is no energy dumping, there is only vital tissue destruction. And the name of the game on vital tissue destruction is penetration.

A bullet that completely fragments on impact will have dumped all its energy on the hide and the tissue just under the hide, and have only produced a flesh wound.

Streamlined, high-BC bullets confer no advantages at the shooting distances of dangerous game. With a zero of 100 yards, practically every cartridge made has a ballistic arc within an inch or two of every other cartridge out to that distance. Streamlined bullets start to show their value past 200 yards, and come into their own around 300 yards and beyond.

As far as KE, it's an interesting thing to know, but doesn't tell everything.

A 230 lb running back running at 18 mph is going to hit a defender with about 3000 ft lbs of kinetic energy. That impact produces a vastly different result than a bullet hitting flesh with 3000 ft lbs of energy. So like I said, interesting info to have and to be able to compare potential results, but doesn't say much besides that.

A sample size of 2...

I used 325 grain Cutting Edge brass solids on both of my buffalo. The first was a frontal shot at 40 yards. The bullet was recovered from a hindquarter and the buffalo died within about 10 seconds and 20 yards. The second was a side shot as it ran by me. Distance was about 40 yards, the buff ran maybe 30 more yards and was down/dead in about ten seconds. The bullet was recovered just under the skin on the far side, having broken ribs and taken out the heart.

For those familiar with the second Hellboy movie, I referred to this as my 'golden army'.

TSX and only TSX for me

While I agree with Philip Swift A Frames aren’t a bad second

I’m no expert by any stretch, but I shot my first and only Buffalo with a 400 grain Woodleigh bonded soft point. It flattened out to 1.2 inch diameter and the Buffalo ran about 20 yards or so and tipped over. The two other guys with me used my gun to shoot their buffs. One never made it out of its tracks, the other about 30 yards. All three buff had a dramatic reaction to each shot. The energy dump and vitals destruction was impressive. All three were broad side shoulder shots.
