I won't shoot a deer over 20 yards and most I have shot within 10-15 yards. My reasoning is that I want a perfect shot and even with the fastest compound bows a deer can jump the shot and duck your arrow. I don't want a deer running around the woods with my arrow through his backstraps. Maybe after I shoot a few more with my ultra quiet AR31 and I see that they don't jump at the shot I will change my distance but not for now.
