As you go up in sabotted bullet weight and powder charge BH209s fps lead gets larger.
That's not my understanding from what i have read about BH at all.. the way i read it was it's about the same as 777 until you start using heavier, say 300 gr bullets and above. then you you can expect a FPS gain...either way he can obtain good groups with a 60 gr charge and .250 saboted bullets!
