bravo2,
Congrats on a nice young buck! Much very good eating there for you & yours, enjoy!
If you're making use of the original Spitfire BHs intended for compound verticle bows I'd suggest you may wish to buy a pack of the Spitfire Max crossbow BH. You can get them in both 100 & 125 gr.
I've not used the 100 gr. BH, but do have and use the 125gr. type. They've not failed me.
Attempts to make use of the original Spits made for compound bows resulted in some strange, though interesting, flight paths. One or 2 of the blades open in flight results in a arrow flying like those the Wiley Coyote gets......swerving off course & coming in to stick him in the b...........LOL.
