Though most BH's will do the job with a properly
placed arrow, large cutting mecanicals are great
for turkeys. They are tough birds...the more
damage you can do (large cut/large wound)...the
better your chance of recovery. When hunting
without a blind I prefer 100 gr. Spitfires/ 1 1/2" cut.
While hunting fron my Double Bull (close shots) I
use Rocket Sledgehammer's/ 3 1/2" cut - 150 gr.

The Sledgehammer will put a real hurtin' on them
birds, but make sure you have enough KE for sufficient
penetration. Last spring I shot this gobbler with my
FX set at 60 lbs/27" draw...

...I didn't get near the
penetration I wanted and ended up bloodtrailing him
over 200+ yds. This year I'll use my Patriot from
my blind, set at 67 lbs.

Just remember, no matter what BH you use....it's still
the shot placement the matters most.

Good Luck
