RE: Sonic Broadheads
I received a free Sonic to try. It does indeed shoot pefect with my field points OUT OF MY BOW. It's tuned to perfection and also groups Muzzy and RM Snypers together as well. It's not so much the broadhead, it's your bow/arrow tuning that is the issue.
The Sonic is a small head, perhaps too small when errant shots happen.
