Greetings all, I have a new R1, comfort tech. I'm looking for a load that has worked well for others. Game is always, Mule Deer, Rocky Mtn. Elk, Bison. What loads have you used? What kind of Accuracy did you get? I purchased Hornady, Custom, 165gr., BTSP. They group around 3" at 100 yards. I'm looking for less than 2" or better. Thank you!
