Thanks to all , the 2 formula is working plus I went an extra 5 inch lbs on the ring caps . Shot several 300-400 gr8 loads the other day and all was good .
Got some nice groups with 300 gr Barnes original and the 400 gr Buster . Three shot groups ran from slightly over an inch to two inches . At max loads .
Will be interesting to try them out on deer next season .
