I think the fact the average hunter is a client hunter when hunting dangerous game says a lot. They also often as a result use lighter firearms, and the PHs prefer a client who can shoot what they bring along, and hopefully has used it before they arrive. A client with a 9.3mm or a .375 who can shoot it would be far better than one with a .500 who flinches with it.

BUT if you have a rifle and rely on someone else getting you out of the shit if it happens, you are carrying an inadequate firearm. In my opinion.

IMO a stopper rifle and a dangerous game rifle are largely the same thing.

If you are a cool shot, a 9.3x62 should be adequate for everything and anything and in any situation ..... Ha ha ... a very cool shot! There is NO WAY I would hunt elephant with a 9.3mm or a .375 if I was on my own. Well I would if I had to, but I would prefer something bigger and heavier hitting.

If I was a guy in the "old days" and shooting hundreds of buffalo, elephant and the like, yes, I might well use something "medium". But you know there are always those times when that bigger cannon is needed.

One might hunt most of the time with that "medium" rifle, but when the heavy jess, jungle needs to be entered, or that wounded beastie needs to be put down, that "stopper" rifle is called for. That "cool shot" might not be possible.

In the older days, the "big bores" started at the .450 and up. Sub .450 to .375, and maybe 9.3mm, .360, .350. .333, .330 etc were medium rifles. To varying extents. Small was 8mm or .30 and below.

If you are a deer hunter, WOW that .375 is big and un-necessary.

If you are a buffalo hunter, that .375 or maybe 9.3 mm is standard and a minimum.
