That's about a foot and a third a second. Don't know if a whitetail can do that in slo-mo......but....

At 10 yds or less....I'll take my chances on a calm deer. I don't think htis is far-fetched, unethical or anything other than shooting a REALLY slow moving deer.

I, too, would caution people about taking moving shots (how do you practice)....but AS STATED......yeah....I'd shoot (at the distance I state).
