In South Africa where mostly PH’s work as independent contractors to outfitters, the rifles they work with and carry, and that are rented to clients, are owned by the PH and not the outfitter. In fact, a PH is normally not employable and won’t be used by an outfitter unless he comes with his own fully equipped truck, and a “battery” of rifles, normally a 30 cal/7mm, a 375 H&H, and then something starting with a 4 or a 5 if they are buffalo or DG qualified (it is possible in South Africa to be DG licenced as a PH only for buffalo).
All of that said, the percentage of PH’s in my country who can afford to own a double is very very low. So in South Africa if a client wants to limit his DG hunt only to a PH carrying a double, that is his right, but would be seriously limiting and denying himself very many excellent and safe hunting opportunities for really no good reason.
Also, we do not much use the term “stopper rifle” where I PH (I am a current licenced buffalo PH). We loosely call the rifle carried by the PH guiding a buffalo hunt a “backup rifle”, of which the majority are bolt action 375’s, a large percentage bolt action 416 or 458’s, and the minority double rifles.
