I don't understand the 9 twist either. Why would 50-100 fps make that much difference that you would want to go to a slower twist when the 8 doesn't over stabilize? For punching little holes short range BR guys are on the ragged edge of stability, the the long range BR guys want to spin em fast. Why wouldn't the Grendel lean more toward the long range theory? Very interesting questons that I'm sure Bill knows more about than I could hope to learn all year. Curious about the reasonings if you're willing to share. Is it more about terminal ballistics?
