Went to big smoke today and got some WIN 760. Loaded with 45.5 gr 760 and 120 hornady BT for a result of 1 3/4 group. Yay. Feel like I'm getting some where. Loaded Speer 145 GS with 45.5 gr W760 for a group of 3 1/4 inches. Bit of a way to go there. Should I go up in 1/2 gr increments or out to a full one?
