No doubt your setup will work with turkeys. I would suggest you
switch to a mechanical broadhead. I'd recommend the regular
Spitfire as opposed to the Gobbler Getter, only difference is the
tip. Sounds like you should probably go with the 75 gr Spitfire,
which has a 1 1/4" cut, compared to the 100 gr which has a
1 1/2" cut. Another excellent choice would be Rocket's 3P
Wolverine - 78 gr and 1 1/4" cut.
I don't think you should worry about getting a pass-through or
not, no guarantee the gobbler won't fly off with your arrow
anyway[:@]. Get your bow shooting well, practice until you
can place that arrow where it needs to be.....above all else,
shot placement is the key
