Jmb ballistics.

There is anecdotal evidence that (1) plastic-tip or hollow-base bullets may have larger errors, and (2) the velocity correction above 3600 ft/sec may predict faster twists than needed. Improvement must await new twist-stability factor data. Don Miller 2862 Waverly Way Livermore, CA 94551 [email protected].
