Twist rate question - 03/09/24
Not that it matters, was thinking about it while reading the velocity/pressure thread. Was always curious how steep of a twist rate before a bullet would plow over the lands rather than spin with them. Read somewhere, perhaps an old Precision Shooting Magazine, not sure. They were playing with barrels twisted with increasingly steep twist rates until they reached a twist rate of 1-4 or 1-3? where bullets would not grab the lands and rotate but rather simply plowed over the lands, developing instant overpressure when bullet meets lands, bullet would tear/strip/fragment on its travel down the bore. Anybody have any insite?
