I have shot dozens of large game animals with slick tricks.
For a fixed blade i have yet to see anything that can beat it!
Blood trails ive had are alot better then when i used muzzy or thunderhead on large game.good luck and have fun...
Why u still having tuning issues?tHAT COULD BE A VARIETY OF THINGS,Arrow spine for poundage,Arrow rest not properly tuned,A bent axle in your cams etc,etc.
U mentioned ur shooting from a machine?Could be a mechanical problem with the machine,I would forget about the machine get shooting at some targets get sighted in by Yourself! start ur sighting in at 15yrds!Once u get them hitting bullseye back it up,Once u get shooting at 25 yrds u will be able to see what ur arrow is doing in flight,like a clearence problem from rest etc.
Good luck,its hard to say without knowing all the bows specs etc.and without being able to visually look at your bow with a arrow knocked to see if everything visualy is tuned to begin with.
