Gents;
I'm a lifelong North American game hunter; I have never hunted Africa, but I have a plains game safari booked for my son and I for May 2025.  I believe I know the answer to my question, but at the risk of beating a "dead horse" (as I'm sure its been asked/answered a lot on this forum), I have a question regarding gun/bullet selection.
The game on our list includes: Blue Wildebeest, Zebra, Impala, Kudu, Warthog, and Blesbuck.  We may also possibly hunt Red Hartbeest and Oryx.  I don't believe my ranges would exceed 300 yds.
I hand load extensively and have a plethora of rifles.  However, due to shoulder reconstruction and cervical fusions, I find that recoil gives me headaches and numbness in my fingers.  Subsequently, I try to avoid unnecessary recoil.
My favorite rifle is a Ruger Hawkeye Hunter, .308 Win, 20" barrel, that I shoot with a suppressor (easier recoil and easy on the ears).  It's topped with a Swaro 3x10.  The rifle is a sub-MOA shooter and I can drive both 165gr Nosler Accubonds and 165gr Swift Scirocco II at 2,700 fps.  My son also shoots a .308 Win (a Sauer), which drives the same bullets about 2,750 fps, with equal accuracy.
I can step up to my 30-06 Spr and move 180gr Accubonds and 180 Scirocco II bullets at 2700 fps; it is equally as accurate.
QUESTION:  With your collective experience, looking at the ballistics of my .308 and the the game that I am planning on hunting, do you think the .308 is amply adequate for the game I am planning on hunting?  Any thoughts would be appreciated.
Thanks,
Bill
