I have experience with the 375 Ruger African. The rifle is a delight to carry and shoots well. The only drawback is the piece of red tire tread they use for a recoil pad. A Decelerator pad makes a huge difference.

I set one up for a friend of mine before he went on safari. He is recoil sensitive and we put the pad on before he fired it. He never had an issue with the recoil.

I mounted a scope on one for another friend and shot it with the original pad. Not ridiculous, but no fun.
