My son used a 7x57 in RSA this past summer. I developed the load for him..... 140gr North Fork Bonded Cores "screaming" along at 2800 fps at the muzzle. Most impressive shot was on his zebra at roughly 125 yards. Frontal quartering too shot. Bullet entered somewhat towards the center of the animal's left shoulder, traveled across the top of the heart severing the major vessels, bullet came to rest just under the skin and rear of the animal's right shoulder. Zebra went down immediately then got up as the tracking dog closed in but went back down in 30 yards or so. Zebra was dead, he just didn't know it.
So yes, I'd use the caliber again on just about anything. An Eland would be about the only African game I'd be a bit hesitant to use it on.
