We've strayed off the topic of 10mm for buffalo but that's ok it's been a good discussion. I did watch a video recently and the PH was of the opinion that only about 5 of 100 buffalo will charge after being wounded. He made a very good point in my opinion it's the buffalo that is mortally wounded but not dead yet that is the most dangerous and prone to charge. Buffalo wounded but not fatally hit nearly always retreat to fight another day. I have little doubt that this has been his experience in 30+ years of hunting buffalo.
