Jmb ballistics.

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.

For "wild-cat" loads (not a true wild-cat as it's a CIP spec'ed cartridge, just not currently manufactured), the 30-.338 Lapua Mag would prob be the next best option; easy to make the brass by necking-down .338 LM brass, and Redding makes dies. But I've heard the velocity advantage over the .300NM isn't very impressive.Compare these ballistic calculator outputs, particularly the "Maximum PBR" range in the first column. The first is with a 20″ barrel firing M193 at 3300 FPS, the second is a 16″ barrel at 3100 FPS, and the third is a 12.5″ barrel at 2900 FPS. These represent my three favorite barrel lengths for an AR-15.Re: Best ballistic calculator ? I mostly use JBM and use Ballistic on the Touch when I'm away from the computer. Ballistic has the option of using the JBM engine, so its results are the same. If you had a small laptop or netbook that you just wanted to haul along to the range, then Litz' program from Berger will certainly work.The drag function to use to calculate the ballistic coefficients. Most commercial bullets use the G1, but for some long range bullets, the G7 or G8 is typically a better choice. Some military bullets fit the G5 and G6 functions better than the G1.Plastic Tip Length. Length of the plastic "ballistic tip" if it exists. Otherwise zero. Caliber. Diameter of the bullet.
