Julian Jackson
Julian Jackson was among the strongest punchers at 154-160 lbs. but he was not able to carry his punches beyond that and he also lost to bigger, stronger middleweights as Mike McCallum and Gerard McClellan.
Strongest puncher P4P to me is Thomas Hearns who could kayo opponents from 147 through 190 lbs.

Yep, Julian Jackson was the hardest P4P puncher of all time.
That title belongs to this man
Joe Louis...............nearly 12 years a champ, defending his title 25 times................
