"also what seems to be the absolute best for stopping or turning a charge??"
Any calibre that you have in your hand at the time !!!

No, in reality, it's not just the calibre but also the bullet being used but in general
as long as you can hit the brain / spine and the bullet penetrates, it should stop a charge.

I had a 338 Win Mag in my hands a few weeks ago and copped an unprovoked charge.
Since it had a scope I couldn't go for a brain shot but hitting it in the neck at close range
was enough to turn it.
