Well, a buddy is using Schwackers, and he's averaging one lost deer a season. I watched him shoot a doe at 30 yards last year, looked like a solid lung/liver hit. We backed out for 45 minutes to let her bleed out, then went in to find her. Long story short, she was still running two hours later, and into the next day, and no blood trail in the snow.
So, I'm not sure what went wrong, but she should have died from the location and angle of the hit.
Mechanicals are too risky and suck. If you can't kill one with a fixed, you don't need to be bowhunting.
Just IMHO.
