That's an awfully small sample size. I'm sure most of us know of grown men that aren't comfortable with a .308 and any bullet weight. I can think of 3 off the top of my head.
Um, without trying to be condescending, who are these three grown men, and what make and model of .308 are they scared of? This sounds like either a first time shooter thing, or an ultra light rifle without a butt pad or some other issue.
