I generally agree, it would not be the rifle for a first hunt to Africa, but subsequent hunts it would work, as long as you limited the range. I am planning on heading back to Botswana in 2024 and am considering taking it with me.I personally would not recommend the 35 Remington on a first safari.
But now that I have been twice, I absolutely would make the hunt as much about the rifle/chambering as I would about maximizing my chances.
I have thought more than once that I'd like to go back for a third trip, and take either my .348 A.I. or my 45-70 (for PG, not DG!).
It would be more challenging, but a normal evolution after having taken 18 animals on the continent.
