Welcome to the best forum Guster,
Seems like someone wrote that the .300WSM is sort of the ballistic twin of the good old .300 H&H ?
If that is so, you certainly have very good ballistic capability for hunting the more open places in Africa, such as most of Namibia, also South Africa's Eastern Cape and Karoo areas.
I have hunted both Kudu and Gemsbok with the H&H version and 180 grain Nosler partition @ a little over 2800+ fps, in Namibia.
That bullet at that speed was IMO just about perfect for those, as well as the other 10 animals I shot with it for a total of 12 with that caliber/load.
Knowing nothing about the bullet you mention, I cannot vote on it but I will say that, for a .30 bullet and open foliage/geography, I prefer the 180 grainers.
And, for the much more common thornbush conditions of Southern Africa (thick forest / rolling hills / a few steep canyons, that are choked with brush), I will always prefer 220 gr bullets (if using a .30 for some reason).
Generally I prefer larger calibers for a "bush rifle", in other words when I am pretty sure I will not be able to see past about 250 yds to 300 yds maximum anyway (across a lake or across a canyon but otherwise almost all shooting is under 100 yds, half or more shots under 50 yds).
Nonetheless, I have on one safari, used the PH's .30-06 in thick thornbush and riverine almost jungle like conditions, with 220 gr Hornady round nose softs and it was a fine combination for this.
So, I have no real valid reason to prefer larger calibers for that type of hunting, except that I am a dreaded rifle nut and prefer to use large diameter/heavy, blunt shaped bullets at slow to moderate speed in wooded conditions where I might see a large animal such as eland, waterbuck, zebra, etc, at close range.
I think for my two pennies worth, if for some unknown reason I wanted to use 165 gr bullets in my .30 of any sort, magnum or otherwise, I'd try Swift A-Frames for accuracy.
Also, not sure if Swift still makes their Scirocco bullets any more but they appear to have been made well for high velocity impacts and reportedly quite accurate in many rifles.
They have a moderately thick looking jacket and the core is bonded to the jacket as well.
If available, I would perhaps give those a try as well.
Last but not least, the old Nosler 180 grain Partition was developed for the .300 H&H when John Nosler had some bullet shatter on a Canadian moose with that caliber, and the rest is history.
This bullet gets over-looked these days but I feel it is a beauty for around 2800 fps, in my personal experiences, using it in Africa and in Alaska (where I live) as well.
The most important thing on this topic is to advise your PH what animals you wish to try for and then ask what bullet/s they might recommend (they see hundreds of animals get shot with various things and so, generally know what works best and what is to be avoided).
In fact, ask your PH for advise on all your equipment, clothing, hunting shoes and everything.
They live there and they know what is what.
