WHAT IS THE TWIST RATE ON THE 19.5 Grendel®, THE 24 Grendel®?
The twist rate for the 19 Grendel® is 1 turn in 8 inches while the 24 Grendel® has a 1 turn in 9 barrel. The difference in twist is due to the difference in velocity between the two barrels and the twist is set to provide optimum accuracy at ranges of 200 yards and out with bullets between 90 grains and 130 grains. The twist rate for the 6.5 caliber must be carefully matched to the application for the best results, and one should note that we do not refer to 100 yard accuracy. This is because the ideal twist for such a range would not work well at longer ranges with heavier bullets.
