These drag functions are calculated using the ICAO standard atmosphere so they will be different from those listed in McCoy's book, Modern Exterior Ballistics. IntLift A modified (modified by R. L. McCoy) version of M. A. Morris' RARDLIFT code with corrections for small arms bullets and medium caliber cannon projectiles.A modified (modified by R. L. McCoy) version of M. A. Morris' RARDLIFT code with corrections for small arms bullets and medium caliber cannon projectiles. Provides interim estimates of lift, overturning moment and yaw drag coefficients. Inputs are very similar to McDrag (above) but it does require the center of gravity location.So, for these six loads, we fired five-round groups from a benchrest at 50, 100, 150, and 200 yards. We zeroed our rifle at 50 yards, so that's our starting point. At 100 yards, the subsonic loads dropped more than 7 inches. The Stinger has about 50% more velocity and it only dropped two inches. Moving out to 150, the gulf between the fastest ...JBM Ballistics has partnered with RIANOV to provide integrated ballistics solutions, including the M06 passive ranging calculator, the SOLO calculator and the CSI.

Drag/Twist Specific Gravities Definition Specific Gravity: The ratio of the weight of an object to the weight of an equal volume of pure water at its maximum density, which is at 4 deg. C.α' = cos -1 (cos (ε)/ [sin 2 (ε)*sin 2 (β) + cos 2 (ε)] 1/2 ) The two equations for ε' and α' give the new elevation and azimuth angles. To correct for canted drop and windage, one only need to take the difference between the initial elevation and the canted elevation and multiply by range.

Northeast. Aug 16, 2015. #9. bigngreen said: Both jbm, shooter and G7 use the same basic solver so if you a large discrepancy between them you have an input issue and if you have to tweek a Berger g7 number in shooter for 1000 yards you have an issue with an input. I have also found this to be the case.
