I am currently shooting game tracker first cut exp 100 gr. mach. BH. I keep hearing that cut on contact BH are the way to go and that mech. are unreliable. Is their any truth to this or am I reading to much? I appriciate all the help that everyone has given me on all my other posts; I am not new to the sport but have just been trying a little bit of everything short of profesional help. Thanks again.

Cut on contact heads are ONE way to go. They happen to be the heads I prefer, myself, but I've done well with Muzzy and Thunderhead replaceables too. Mechanicals aren't as unreliable as they were some years ago. In fact, most of today's models seem to be getting the job done for a lot of people. But still... I'd rather my broadhead's blades be out there and ready to cut when they hit the target instead of relying on them to open up after they've made contact.
