I was always told by both my grandfathers and my father that is was total waste to shoot multiple shots if the first was a good one at Moose, Red deer, Reindeer and Roe deer as it would not kill the animal any faster
From my own experience I think they were right, but I don't know how it is with buffs.
They must have been sharp shooters using .223 during the economic depression or war years.
I am fine with that theory when in the woods and I can not see where the animal went after I shot.
It's the ones in the open like this that get the bolt moving on my rifle.
I figure sneaking up on any animal and it does not know you are there at all and does not get any chance to get adrenaline going will facilitate a faster demise.
My first Eland took 400 grains in perfect boiler room shots and would not die.
800 more grains he was done 300 meters later.
I am sure the first two shots were lethal, but there was not enough bush to hide him from me.
So, the bolt started going.
I am sure with Buffalo everybody just wants it to stop moving.
Then there is no danger of having to go in that bush to find the result.
