[QUOTE="KRP, post: 474805, member: 9969"] 10 twist chambered in 6BR. The calculation is flawed because the formula is for muzzle velocity. Calculate the RPMs of the bullet at your desired range(I'm of no help for the math/info to do this) and enter it into the formula and see what you come up with. A 10%(for example only) loss in velocity does not equate to a 10% loss in RPM after the bullet leaves the barrel. [/QUOTE]
