Never ever a cartridge has killed an animal.
It is the bullet, that kills.
The bullets that failed in the 60's and 70's does not exist any longer, since decades!
With todays premium bullets, the 10,75x68 kills like every other cartride in it's class.
Sometimes it makes sence to look around the corner carefully......may be, the world has changed.

That is an extremely sound reasoning , HWL . Technological advancements in bullet manufacturing have certainly come a long way ... Since the last 60 years . I also have no doubt that the modern Woodleigh bullets are far more sturdily constructed ... Than the RWS brand bullets of our time .
However , the reason why I do not personally recommend the .423 ( 10.75 × 68 mm ) Mauser as a dangerous game calibre ... Is because the cartridge case holds too little a charge of powder in proportion to the weight of the 347 grain bullet . I have no doubt that the bullet itself ... Shall remain intact , when fired at thick muscled dangerous game .
However , the cartridge itself cannot burn a charge of powder large enough ... To carry a 347 grain bullet through the hide of thick skinned dangerous game , with 100 % reliability . When a a royal Bengal tiger or forest panther charges ... It's chest muscles tense up . And this is what proves to provide the greatest degree of resistance to small arms fire .
I have another article on my IPAD ... Which I shall be posting here , shortly . It is from Man Magnum magazine's 2015 edition . The article details the author's attempts to hunt a large South African male cape buffalo ... By using a .423 ( 10.75x68 mm ) Mauser calibre bolt rifle .
The author uses hand loaded cartridges ... With the bullets being 347 grain Woodleigh soft point and solid metal covered bullets . By the end of the article ... The brute ends up requiring a grand total of 5 cartridges to be laid low . A post mortem reveals that all 5 of the bullets had hit the Cape buffalo ... In a vital region , right behind the shoulder . However , only the 4th bullet manages to successfully rupture the Cape buffalo's heart .
The author , then goes on to note ... That the .423 ( 10.75 × 68 mm ) Mauser worked successfully on a West African forest buffalo , during a previous safari . However , he declares the .423 ( 10.75 × 68 mm ) Mauser to be marginal ( At best ) for hunting dangerous game .
Now , yes . The world is changing every single day . Things certainly have changed a great deal ... Since the 1970s . However , when a person in 2015 experiences the exact same things with a calibre ... which you did , in the 1960s and 1970s ... Then , that is a very good indication ... That , perhaps bullets were not the only reason for the short comings in the.423 ( 10.75 × 68 mm ) Mauser ... As a dangerous game calibre .
