[QUOTE="25.06, post: 810658, member: 22714"] Evening everyone, Interesting Topic for the Forum. I appreciated the comment by Bart B with regards too high RPM's influencing accuracy. I did a quick spreadsheet for twists, 9-10-11-12. Velocity range of 2300 to 2700 FPS. Interesting to me was that the difference in RPM's between a 9 twist and a 12 twist was approx. 46,000. Trying to analize what I'am looking at, I reviewed Lyman's most accurate load for a 180 grain Ballistic tip bullet. It produces RPM data of 181,728 based on a 10 twist at 2524 FPS. My question is: When does RPM's and at what rate of spin come to influence a load. Thanks for listening. [/QUOTE]
