I've killed 38 Biggame animals with a recurve & mostly wood arrows with a 3 blade Broadhead-from 45#s to 60#s-mostly 55#s.
Black Bear (55#s)-Elk (55#s), Whitetail (45#s55#s), Wild Hogs (52#s).
I've shot 2 blade, 3 blade & 4 blades with recurve& a 3 blade always flys good.
I now shoot a compound (100+ animals) & since mid 70s have shot 3 Blade Rocky Mountains. Currently 3 blade Ironheads.
Pic-1965 55#s shot at 30 yds& traveled 30 yds.
good Luck-go with a 3 blade-shot placement makes the difference.
