big game gives up 80 or so FPS to RL17 . I never had accuracy troubles with RL17 . this is a target from when I was developing the load . the top three spots are the RL17 in my rem rifle . left is 48.0 , center is 48.5 , right is 49.0 . shot from 200 yards . the big lower spot on the target is my Tikka using IMR4064 . also shot at 200 yards . at the time the tikka had a lower power scope , hard for me to shoot small with a low power scope .
