Those are hotter than the Underwood offerings.
Thanks for the concern though.
Those numbers would put swamp fox at the top of the list. Do you have any way of backing up those numbers? What gun were there chrono'd on? Video proof? But I wouldn't considereing the major bands mostly rate below 500 ftlbs I would still call Underwood 'hot'.
More importantly to me is that swamp fox is twice as pricey as underwood. Would you rather have 500 rounds of swamp fox it or 1000 rounds of underwood? For those on a budget that is often the choice.
