I personally use bipod style shooting sticks. I have a heavier xbow 9 plus pounds and a bad left shoulder. This combination is what led me to trying them. I absolutely will never again hunt without them. I am a really good shot free hand but my bipod sticks have truly made me a better shot. At 65 yards I shoot a four arrow grouping slightly smaller then a grapefruit. I do match my arrows to my xbow and only shoot arrows with a .003 or smaller strangeness factor, the correct spine and a 1 grain weight variable in weight/dozen. Good equipment that I'm comfortable with coupled with good adjustable shooting sticks are what makes my shot groups so small.
