I've read several of your posts mentioning your interest for the likes of 505Gibbs, 600 NE etc. Have you been on many hunts (as a client) where you ended up bringing a much larger cartridge than what your PH was carrying?
I wonder how rare of an occurrence that would be.
IvW is right. Larger is not always better. As a matter of fact, it can actually be downright counterproductive if you aren't able to manage the recoil. And the unfortunate reality is that the bulk of client hunters who come to Africa, can't handle the recoil of these calibers. Usually the .450 bores are the upper limit of what most client hunters can handle. Especially these days.
In the days of commercial ivory hunting, the .577 Nitro Express was an almost universally accepted choice by the professionals (like Frederick Banks, Quentin Grogan, James Sutherland, Count Potocki). They never complained about the recoil. Yet, today most hunters cannot handle the kick. Is it because men have become physically weaker in modern times ?
No. The answer is because:
In the old days, the professionals had plenty of opportunity to practice with the big bores since bag limits were nonexistent. Thus, they became proficient with them over time. In modern times, most hunters won't accumulate the kind of practice necessary to be able to shoot these larger calibers with any degree of accuracy (exceptions notwithstanding).
I can shoot the .505 Gibbs and .600 Nitro Express with accuracy, but (without any intention of gloating) I've been hunting in Africa now for 49 years. And I've shot most (but not all) of my dangerous game over the years with the .375 Holland & Holland Magnum as well.
Shooting a .505 Gibbs or a .600 Nitro Express with any degree of accuracy needs a lot more practice and time than (say) a .375 Holland & Holland Magnum or a .404 Jeffery or a .416 Rigby or even a .470 Nitro Express (among others). It's not for everybody.
I've always been passionate about the .505 Gibbs and the .600 Nitro Express. And after firing them, I realized that (while recoil is definitely very noticeable) I can learn to mitigate the recoil with some practice. Maybe it was actually more difficult than I thought it was, but if you love something... then you become willing to take a few kicks in order to get used to it. Here, I should also mention that by the time I first tried either of these calibers... I had already been hunting in Africa for more than 20 years.
I eventually did hunt an American bison with a .505 Gibbs and a Tanzanian hippo bull with a .600 Nitro Express. The photos can both be seen on my media page. I unfortunately don't have access to them at the moment since I am typing this using my smartphone. And the photos are saved in my IPAD at home (which I usually use for commenting on these forums).
I'll definitely be hunting with both of these calibers again at the next possible chance that I get. But for a novice client hunter, I will always advise them to go on their first African safari with a .375 or a .404 or a .416 or a .458 of some sort. Unless, of course... If they can actually handle the recoil of the bigger bores.
I eventually learnt that I personally can (speaking for myself). But every hunter should exercise their individual discretion and assess for themselves as to whether or not they can comfortably handle a big bore. Rather than just try to do it forcefully.
