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.
