In all the observations about bullet softness and ability to penetrate or lack of it, nobody has cottoned on to the fact, or at least mentioned it, that in all calibres the long heavy bullet provides stability and penetration rather than a short for calibre lighter bullet. This is the very reason why the smaller 7x57 nd 6.5x54 cartridges proved quite capable of racking up good dangerous game kills in the hands of a shooter who could place the bullets to do the damage. Bell being perhaps the most famous but other hunters of his era in Africa also using these calibres for big but less dangerous game. The 9.3 and 375 cartridges also built their reputation on the long heavy bullets they used. All these cartridges operated at moderate velocities.
Taking a 350gr .423" bullet, no matter how strongly constructed or how fast it is driven, is not the key to a reliable and consistent big game killer.

There is a reason why the 375H&H, 404 Jeffery, 416 Rigby and 425 Westley Richards earned such magnificent reputations, and for the first two such common and widespread use, as large dangerous game killers in Africa. It was the long heavy bullets, irrespective of construction and velocity, that all these cartridges had in common that made their reputation, not short stubby varieties.

I have to agree.

If I had the choice between the cartridge 10,75x68 and the cartridge 375 H&H Magnum, I would choose the latter and with a long and heavy bullet. I also regulated my MS rifle caliber 9,3x64 with a 320g bullet just in case, but it's also not my first choice for hunting DG.

Concerning the cartridge 10,75x68, what is being said about modern bullets and various powder charges that can improve the performance of this cartridge is all theory. You cannot shot a buffalo or a elephant with Quick-load or any other computer program.

All true except for the last sentence.

What kills big animals. Penetration and calibre width. Sectional density and adequate velocity is the key to penetration and related of course to bullet weight to the calibre size. The width of the wound channel is the other factor.

And yes. the reason the 7x57 with 175 solids was a killer, the .318 WR with 250 gr solids killed many thousands of buffalo as did the 8x60's/8x57s.

I don't know if 320 gr 9.3's and 350 gr .375's were available back in the day? The usual was the 300 gr for the .375. ut a 287 gr 9.3, 300 gr .375 and 400 gr .416/423/408/411 etc all have adequate sectional density.

The last paragraph, no quick load can not kill a buffalo but the 10.75x68 can and has killed water buffalos. Keeping claiming otherwise is silly. Aussie owners of 10.75x68 have used them on water buffalo. Buffalo are not armour plated. I would be willing to use a 8x68S, a .300 Magnum, a .318 WR, a .350, .360, 9.3mm, .375 NE and many many other a choice for buffalo. With suitable bullet and if legal. They haven't become invinceable a hundred years later. Indeed a hell of a lot of Aussies just use their deer medium game rifles to shoot a water buffalo, a .308 or .30-06.

BUT having big bores I DO CHOOSE to use them isntead. Why not? They are fun. And if the beastie decides once every ten or twenty buff to li;; you instead, they are better insurance. My next buffalos will hopefully be taken with the 10-bore and the .404.

Hype and marketing MS also does not kill a buffalo. Their "invinceability" sells expensive hunts. But a good bullet in the right place does kill very well.

Anyway, they are good fun to hunt, and more fun when or if they unfortunately do not drop instantly and excess fun when the run down a hill towards you.

I have only shot two elephant, both with the .450 NE and 480 gr solids. Both were brain shot with the first shot. Other insurance shots were taken afterwards though.

I do prefer something with more grunt with elephant. If I had one I would choose a .500 NE or .577 NE. Knocking one over with a less than perfect brain shot may be advanteguous.
