Trust your opinions here and have a question. I been using shock wave mech. 100 gr this season on deer and have took a doe so far. The heads worked without flaw. 20 yrd shot pass through the heart, deer ran less then 20. I'm going on a hog hunt in Dec. in Texas and was wondering if I should stay with the mech. or go to a fixed head. I'm sure a hogs skin is thicker, just wanted your input. Thanks in advance.
