From your own article.
“The potential force transmitted from a bat to the tibia at the time of collision is 8,000 lb, three times that of the bullet 626 lb.”
8000/626=3 (hmmmmm?)
Think of a bat as about a 20,000 grain bullet traveling close to 300 fps. 1/2 mass x velocity squared.
NO pistol bullet comes remotely close to a Louisville slugger signature edition.
Anyone expecting a 45 or any pistol bullet to “knock down” anyone is in for a sad wake up call. Pain, fear, surprise and CNS damage may cause someone to go down immediately. But “knockdown” as in raw knockdown power is pure fiction. Its pure Hollywood.
I agree that no bullet knocks a man down by energy, any more than it does a deer. A deer goes down based on what part the bullet hits.
