According to Sierra the 300 SMK will stabilize in a 10 twist at 2400 FPS comfortably. The tech that I spoke with stated that the 300 SMk at a muzzle 2000 FPS would have a stabiblity factor 1.25

While I agree that this should be the case, I have seen where it is not. for example a friend of mine has a 338WM that is very accurate with the 225gr Accubond. he wanted to shoot the 300gr SMK that I shoot out of my 338LapuaAI. this gun went from shooting 1/2" group's with the AB to 1/2 foot group's with the 300gr SMK, and yes it was checked at being a 1-10" twist
