Top 9 Ballistic Missile Submarines In The World (2022).The JBM Ballistics engine utilizes Litz-derived Ballistic Coefficient (BC) values, based on field testing by Bryan Litz, a champion shooter, aerospace engineer, ballistician, and author of the highly regarded Applied Ballistics for Long Range Shooting. The BC is a measure of the capability of a projectile to overcome air resistance in flight. It’s a function of weight, … Bullet Lengths I am in the process of adding bullet lengths to the library so that the drift can be easily calculated. Since I cannot afford a box of every type of bullet to measure them, I am asking for your help to populate the length values. 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.Ballistics Calculator - Free. BallisticsARC uses the JBM ballistic calculator, identical to both the Shooter and BallisticsAE apps. This is absolutely one of the most powerful ballistics engines out there, and it gives you the exact same computing you'd find in every other calculator on the market.A ballistic coefficient is a comparative value for a given bullet, showing its relative resistance to drag versus a model projectile that has an empirically established set of drag characteristics. There can be as many model projectiles as there are different bullets, but which ballistic coefficient type is used depends on the model and how ...JBM Ballistics "Trajectory" calculator (not the "simplified" version). You'll need to play with your numbers and find the best "Maximum Point Blank Range." That calculator will allow you to input your vitals diameter (5", 7", whatever). Check the block that says "Zero at Maximum PBR" so that data gets included in the output chart.Trying to produce a chart for .308 168 Sierra Matchking. Using BC of .462 and with G1 specified it shows I need to hold over 414 inches at 1000 yards. If I change nothing other than changing G1 to G7 it says I only need to hold over 295 inches. That's a pretty huge difference. Been trying to...Ballistic Coefficient (Velocity) Calculate a ballistic coefficient from near velocity, far velocity and distance between velocity measurement points. Ballistic coefficient is calculated for input drag function.Plastic Tip Length. Length of the plastic "ballistic tip" if it exists. Otherwise zero. Caliber. Diameter of the bullet. Muzzle Velocity. The velocity of the bullet as either (1) measured at some distance from the muzzle or (2) as estimated from reloading data. The on-line ballistics page can correct for the distance to chronograph.Maybe 1 in 250,000 shooters have actually tested, created, and built special software to use a custom drag curve. OP, have you accounted for higher temperatures than the bullet's BC is based on. Most bullet BCs are based on an atmospheric standard like ICAO, Std Metro, or Std. Army. All three at 59degF.Don Miller developed this formula as a more accurate way to find an ideal rifle twist rate. Whereas Greenhill was more of a generic formula, Miller's uses more characteristics of a rifle bullet to arrive a a more tailored solution. m = bullet mass in grains. s = gyroscopic stability factor (dimensionless)Ballistic calculator. Strelok is a ballistic trajectory calculator.Small, handy and accurate. Field-proven accuracy since 2001. Supports imperial (yards, feet, inches, etc) and metric units. MIL and MRAD - this is the same! Input all parameters, push... Lapua Ballistics. Lapua Ballistics is the ultimate 6DOF ballistics tool for mobile devices.Calculates the power factor and checks divisions for IDPA, IPSC, TSA, USPSA and SASS. Output shows whether or not the division is made (green/red) and by how much in percent. Calculates the free recoil energy and velocity using firearm weight, charge weight, bullet weight and firearm velocity.Maybe 1 in 250,000 shooters have actually tested, created, and built special software to use a custom drag curve. OP, have you accounted for higher temperatures than the bullet's BC is based on. Most bullet BCs are based on an atmospheric standard like ICAO, Std Metro, or Std. Army. All three at 59degF.The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of the bullet. The velocity of the bullet as either (1) measured at some distance from the muzzle or (2) as estimated from reloading data. The on-line ballistics page can correct for the distance to chronograph. (The velocity lost traveling to the chronograph.) Nose Length. To make one, first generate a come-up table, using one of the free online ballistics programs such as JBM Ballistics. You can also put the info in an Excel spreadsheet or MS Word table and print it out. Above is a sample of a data card. For each distance, the card includes drop in inches, drop in MOA, drop in Mils.Hornady Ammunition Ballistics - 308 Winchester. Jump to a ballistics chart: Hornady American Gunner 155 grain BTHP Match | Hornady American Whitetail 150 grain SP InterLock | Hornady American Whitetail 165 grain SP InterLock | Hornady Black 155 grain A-MAX | Hornady Black 168 grain A-MAX | Hornady Critical Defense 155 grain FTX | …The velocity at which the ballistic coefficient entered above is defined. If you only have one BC and no velocity information, use the average of the muzzle velocity and terminal velocity so that you get a new ballistic coefficient representative of the velocity range you are using.JBM Ballistics has always been my go to for comparing ballistics, answering what-if questions, and more. Every time I try to open their web site, it just sits there and spins. Does anyone out there know what's going on? Thanks. Reply. sp6x6 Well-Known Member.
