THE VERDICT Nationwide is better than Mercury overall, per ...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. Don Miller 2862 Waverly Way Livermore, CA 94551 [email protected] statistics [calculated Wednesday, March 20, 2024 at 16:25 MDT] are based on the last 31 days of bullets chosen from the bullet library.

The free recoil velocity can now be found. V F = (0.000745 slugs * 2700 f/s + 0.000177 slugs * 4700 f/s)/ (0.217 slugs) = 13.1 f/s. And the free recoil energy is given by.

Its effect is negligible at medium distances, but becomes important around 1000yds and beyond, especially because it can add to other minimal errors and keep you off target. Coriolis effect affects everything not firmly attached to the Earth’s surface. It affects fluids, like air and water, as well as floating and flying objects like ships ...4. Applied Ballistics. The Applied Ballistics mobile app is certainly my favorite ballistics calculator application for Android and iOS. Yes, it’s expensive, costing $30, but in my experience, no other ballistics calculator comes close to the functionality you get with this application. Applied Ballistics App.I've found them listed in one book, Ballistics of the Future (see below), and have listed them here for anybody that does not have access to this book (only fourth order was shown). For two equations, dy/dx = F(x, y, z) and dz/dx = G(x, y, z), a single integration step of h is defined by:The G7 Ballistic coefficient does a better job of predicting the trajectory of modern long ogive, boat tail bullets to longer ranges than the G1 standard, however, it is still not modeling the exact Cd value or shape and will result in errors. Utilizing the popular and well-designed JBM ballistics code, Table 1.The JBM Ballistics Range Card (shown below) lists ranges down the two outer columns and different ambient temperatures are shown across the top. Each intersection of range and temperature shows two numbers. The upper number is the elevation adjustment in clicks and the lower is the windage adjustment in clicks needed for a 10mph direct crosswind.A drag function is tabulated for a standard bullet of known shape. This is done by measuring the drag of the standard bullet. This standard bullet has a ballistic coefficient (BC) of 1.0. Other bullets of the same shape but different size have different ballistic coefficients. The drag function and BC are then used to calculate the drag ...August 1st, 2013 Updated URLs for JBM Online Ballistics Program. The web-based JBM Ballistics Program is one of the most sophisticated and accurate ballistics calculators available — and it's free. The latest version of the JBM Trajectory Calculator includes field-test-derived actual G7 BCs, as well as bullet drag data from Lapua's Doppler radar testing.

You can, but not very accurately. If you look at the bullet drop for two bullets, one with a BC of 0.5 and the other with a BC of 0.55, you'll find that the bullet drops at 300 yards with a muzzle velocity of 3000 f/s and a 100 yard zero, are -10.9" and -10.7" respectively. So if you can shoot groups less than 0.2" at 300 yards, have at it.Changing Variables of Integration. From the discussion on CD and KD, we know that the acceleration of the bullet is. a = - k v + g. where. k = = p/p 0 G (m)/C. Rewrite the acceleration as a derivative. a = d u / dt = - k ( u - w) + g. Define a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x ...Most ballistics software programs will calculate MPBR for any given bullet and velocity. If you don't have your own ballistics software program, there are excellent calculators available to use for free at the JBM Ballistics website. ... This table was calculated using the JBM calculator linked above. Calculated Table MPBR: Range (yds) 50 ...if your stuck with a MIL/MOA scope for hunting, you could tape over your 1/4 MOA turret hash marks and convert them to "rough mil" to match your mil reticle. just place a new hash mark on the tape every 7 clicks for 1/2 mil and a large hash mark every 14 clicks for a full mil. (.25 x 14 = 3.5inches) thats only 1/10 inch off at 100 compared to a ...For the less eager, there are several approximate methods of calculating the required spin for a bullet. The simplest is the old Greenhill formula: T = 150 / L. where T is the twist in bullet calibers, and L is the length of the bullet in calibers. Unfortunately, it's not a very good method, but I include it here to show that longer bullets ...

The formulas for the drag function as a function of the drag coefficient can be found here . For any bullet, the drag force must be the same no matter what drag function is chosen since the drag force is physical and depends on the shape of the bullet. This means that the following equation must be true. G (M)/C = G (M)/C.Drag Function Array Conversion. Convert multiple ballistic coefficients and find the best new drag function.

When talking about ballistics, the Coriolis Effect refers to the deflection on the trajectory of the bullet generated by the spinning motion of the Earth. Its effect is negligible at medium distances, but becomes important around 1000yds and beyond, especially because it can add to other minimal errors and keep you off target. Weight: 3.1 oz.

k 4 = h F ( x n + h, y n + k 3 ) The equations of motion for a bullet in flight, are simultaneous coupled differential equations. Specifically three equations for acceleration, position and spin. These equations may have been transformed using the substitution: d u /dt = d u /dy dy/dt = d u /dy u y.

Ballistic coefficient (BC) is a fudge factor that rates how efficiently a bullet flies. ... This information is a pain to find, but thankfully, the folks at JBM Ballistics have compiled lots of ...

Many modern ballistics programs, including the free online JBM Ballistics Program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan. [Editor's NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly ...This book, among other things, includes software and experimentally measured ballistic coefficients for 175 bullets. The bullets have been added to the JBM Bullet Library using the G7 drag function bullets measured by Bryan are denoted by " (Litz)" in the description.

Includes latest commercial data and military coefficients established at Aberdeen Proving Grounds. Based on this data, I am confident that best COL length is between 2.53 and 2.60 resulting in sub MOA performance. A bullet seated less than 2.53 is near to the curved o-give. I would perhaps settle on just less than 2.60, say 2.58 for future tests on the Sierra 120 grain. Speed is 2892 fps at the muzzle.
