"Those who might think the round is too underpowered for buffalo, merely need to try it."from posting above.

Roger that, I took a buffalo with a 420 grain cast of my design and can assure you that it is more than enough, the penetration was complete through both shoulders. I would like to have recovered the bullet to see how it held up but it must have been plenty good enough, hard to argue with the results.
