I took a 3-rifle battery on my very first safari, which was a 24-day affair in Zimbabwe. Since I had everything from Grysbok to elephant on license, except for a lion, I figured I needed a light, medium and heavy rifle. I took what I had at the time:
Ruger M77 in .270 Winchester
Ruger M77 in .300 Win Mag
Colt Sauer in .458 Win Mag.
I used all of them, but used the .270 & .300 for everything except 2 buffalo and the elephant. I did another 24-day hunt in Botswana and took 3-guns but then it was:
Model 70 in .416 Hoffman
Model 70 in .338 Win Mag
Beretta A-302 in 2 3/4” 12 gauge.
These days, I usually take a 2-rifle battery consisting of my .338 and .416. If I only take 1-rifle it’s usually my .375 H&H.
