[QUOTE="ricka0, post: 37100, member: 3086"] Over stabilize may be a misnomer, but it's what the literature generally uses. ANd yes, it's far batter to over than under. Under is what killed the Rem 6mm and made the win 243 dominate (the .243 could stabalize deer sized 100gr bullets) R CROSS F will kill you at too high a angular velocity, well known and understood by ballistics experts, hense the GreenHill formula. As my pal Daniel Lilja says [URL=http://www.riflebarrels.com/faq_lilja_rifle_barrels.htm#twist rates]Daniel o Twist[/URL] [I]Target shooters, especially bench rest shooters, like to use the slowest possible twist rate they can get away with in an effort to get the very ultimate in accuracy from their barrel.[/I] To give you an idea of the R cross F counterintutive force, pull your hard drive out - and while the computer is running twist the drive. A cheapo 7200 RPM IDE drive will give you the odd R X F force. For bonus points, try this with a 15K RPM SCSI drive (mine are hot swappable, not cabled so I can't test this [img]images/icons/frown.gif[/img] ) [/QUOTE]
