Totally OT, but lets face it.
MS is a PH & in the business to sell hunts. Some of his videos will attract all sorts of clients, that, unlike most of the folk on this good forum, might think hunting is a form of status & valor, or some first time clients that knows no better but decides to book due to the fact that that MS is well known & seems to be the expert thanks to his videos making it to every corner of the world.
Unfortunately for him, these antics don't sit well with everybody, and though I don't know him & don't personally agree with all his portrayed actions or choice of words, I have to admit that he is a good shot. Beyond that I have no doubt that he is a likeable person away from the camera.
I'm sure the PH's can elaborate on some absolutely weird experiences with clients. The stuff I heard from PH friends & outfitters regarding
some of the types of clients... One that arrived for a DG hunt with a brand new rifle & scope that gets mounted for sighting in on African soil then asked the PH to shoot it first. Clients arriving in a private helicopter, requesting the animals to be driven or lured towards him so he can shoot & get out of there for his next appointment. Another asking the PH if the cameraman can edit the video to reflect the hunt as a dramatic life & death situation if they don't get charged! Quite a few other cringing stories btw..
The point is, Not all hunters have the same knowledge & values towards our loved activity. The PH needs to put food on the table & when the client is willing to make it rain, the lines can get a bit blurred.
Back to the OP's question, getting a bigger caliber is always a good thing as long as you can manage to be comfortable with it as much as your regular firearms you use for North American game &.... its a 404Jeff
Wasn't the Chadwick ram (Stone Sheep) taken with a 404Jeffery?
Its a lovely caliber, hits with authority & can be used on just about anything. Its perceived recoil to me is not as sharp as the .375 or .416, rather a push than a shove.
Either way, I hope we get to see what the OP finally decide on.
