Calculate a trajectory card from bullet, velocity, firearm and atmospheric parameters. Density is calculated using input density altitudes. Muzzle velocity is found by using linear interpolation between two velocities measured as a fuction of temperature. Explanation of termsBallistics calculations and formulas for small arms. Additionally, the calculated elevation is 6.10 MOA. This calculated value is shown above the trajectory table in the output of the calculation.

Jut go to JBM ballistic calculator and use the same bullet for different twist or different velocities. You should be able to understand it better. Going from 20" to 22" might not be significant change in velocity, but going from 16 to 24 could be, it could be critical enough whether your bullets tumble or stay true.

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.
