I have a 10 point, a Excalibur Exocet And a Parker Tornado, the suppressor quited the Tornado down about 50 percent the others have suppressors on but they did not help as much. As has been mentioned before if you keep your shot under 25 yds they are faster than the deers reaction time for sound,I personally do not shoot if they are looking right at me light is much faster than sound.
