RE: Fixed...or...Mechanical
I hunt a lot in suburban areas around St. Louis. I use rocket hammerheads 3 blades 2" dia. Hit them right and I see most of them fall. I don't want to be chasing them through neighbors front yards. I wait for perfect shots at close range. Have had great luck so far. Most shots pass right through and they even know they are hit. They run off a little ways and look back to see what spooked them. Pretty soon they start wobbling and fall over. That is the way I like it, what an awsome site. We can buy unlimited doe tags in St.louis Co. so I get lots of practice.
