Use IMR 4350 with a 150 gr. bullet. Use both Sierra 150 gr. Game King BT or Noslar Partition. With 60 gr. of 4350 you will make 3000 ft/sec. I've tried using a 140 gr. bullet but I've found that my gun likes the loads with the 150 gr. better. Each gun is different so enjoy your experimenting. With 4350 you can use 63 gr. which will give youjust over 3100 ft/sec but after much experimenting my gun performed best at 60 gr. As stated each gun performs different. I've also worked some loads with H4831 and H1000 but I have had better accuracy with the 4350.
