You must be mistaken, M&S confirm that the .45 Long Colt one shot stops stumps 97.8564347% of the time.

I am glad to hear you are OK, considering the potential for grievous injury.
The most painful bounce-back I had was a 9mm returning to my ankle from about 15 yards.
I had a bullet bounce back and smack me in my shooting glasses a few years back- that will get your attention in a hurry!
