I have hunted Africa with my own rifles in 270, 30-06, 338 and 416. Depending on game they all worked great. The 270 would have been "enough gun" for at least 90% of the species hunted.
That said, I no longer haul firearms overseas. The hassle and expense is simply not worth it. Many PH's will only charge you for the ammo, some will rent suitable rifles. By the time you pay excess baggage fees, firearms permit charges, handling fees, ammo taxes etc., it is not the best route to take IMO. If you want to sight-see where are your guns? Who has access? Hotel security? Many outfitters and PHs have excellent arms. My experiences with this policy include Africa, New Zealand, Argentina, Scotland and England and I used some of the finest, even custom firearms I can only dream of owning. JM2C
While a lot of my pleasure is in developing my own loads in my own rifles and then hunting with them, this is the way I'd also go in the future.
