I have no personal experience with buffalo, but I have heard they are dangerous. I would rethink your position on accuracy unless your main fear is making it mad! I understand very healthy ones can kill you better than wounded ones?

Anyway, I also read, years ago, that if you spit in their mouths they will run away. All you got to do as they charge is work up some spit! ref. Bill Herter- how to get out of the rat race and live on ten dollars a month -I think?

Maybe load one for birds and the other for buff?
