My old Hoyt was 72# and shot 430gr arrows at 272 fps ( easy to remember lol ).
Had a buck run some does in and one stopped on a mound on the ridge.....basically even w me ( 18ft base of treestand ). I had drawn as they came by and she stopped on that old groundhog mound. Which I had measured that morning coming in to stand.
45 yards.
Lined up rhe few openings in branches for clean path and let er go.
My HHA sight was set for 25 yards. So i had to hold on her backline to drop it in w that setting. Didnt have time to adj sight.
She tried to duck it, but the arrow got their quick enough to blast the spine. Fletching visible ( buried to fletch). Magnus stinger 125 e bleeders was way out the other side.
Which when she rolled meant bye bye carbon arrow.
Man that arrow got there fast! Was first yr back w wheels since injury forced giving up trad for a while.
Sometimes, even in archery......a little extra zap can help save the day. Lower arch, less time of flight and enough to plow through when it got there
