[QUOTE="benchracer, post: 958097, member: 22069"] Will gladly continue to post results as I have them. According to the information and spreadsheet/calculator posted by Mr. Courtney, a 12 twist is sufficient to stabilize the 69 SMK, even at lower velocities, but that same information also shows that a lower level of stability can reduce bc. When I shoot this load at longer range, I hope to determine whether or not it is stable enough to get the full bc value. Michael Courtney's research was a real eye opener and an interesting read.
