So I am in my back yard shooting my PSE, and for some reason I can be dead on some days and destroy a beer can from 30 yards all day. And others I will always shoot the right and up about 3-4 inches. Is this from my release being to tight or loose on my hand? Maybe I am dropping the bow, or jerking the trigger. And help will be welcomed. This is the first year for me in archery, and I really want to harvest a deer this year, and I dont want to blow my chances with a junk shoot. Thx.
