My 700 ML shoots 1 inch groups at 100 yards with Barnes MZ 250 grain sabots with two 50 grain pyrodex pellets and a cci 209 primer. My CVA hunter bolt shoots a 1 1/2 inch group at 100 yards with the same charge and primer as the 700 ML. the key is the cci 209 primer with any other primer my groups open up alot.
