I came to the conclusion that it is finaly time to move to expandable blades and try them out. Today i shot my bow with my broadheads with three different heads which are muzzy 3 blade100, Thunderhead 100 and muzzy 4 blade 100's. i couldnt not get any of these to group they way i would want them to. i was getting so frustrated. So i was debating of a expadable head, but i thought and heard alot of people say some dont open on contact and some are weak. I want the accuracy i have with my field points as i would if i was hunting with a broadhead. Do you of you ahve any information on an Expandable that is Tough, Strong, opens on contackt always and is very accurate like a field point. Please i need your help, and if you have any other broadheads that you with would work for me let me know? I would really apprecate your help!
