Mine was initially purchased as a standard stock, and I put a compact stock on it for my daughter. She shoot 1 3/8 oz Tss 9.5's with a Tightwad choke. When I use it, I shot a .582 undertaker and 1 5/8 tss 9's.
Initially I started out with an Indian Creek .555 but after several missed turkeys (using a Burris Ff2) I decided it was too tight to hunt with.
