Just for grins I ran some numbers using the
Taylor Knock Out Factor formula comparing the .308, .22LR standard velocity, and a one ounce lead ball .75" dia. shot at an average speed of 75mph or 109fps
.308 = TKO of 18
.22 = TKO of 1
1oz sling = TKO of 5
But as you say, actually hitting the target would be a prerequisite.
Here's the chart form the article on TKO:
