Modern riffles have more than 1200 mts per second of speed. The good news is that the cost of a smartphone-based ballistic calculator ranges from free to \$29.99. Enjoy, play around and learn! Just enter your bullet weight below and its velocity It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. Use this online calculator and find the muzzle energy in foot pounds and joules. Foot pounds of energy from a pellet or rifle is easily calculated with the speed of the projectile and the weight in grains. Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle. This is a general information calculator and there may be additional parameters that can have slight effects. About the Velocity Estimation Calculator How does it work? Muzzle Energy will be rounded to the nearest whole number. The MV Result will warn you if your velocity is too low. Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? Ballistic Coefficients (Velocity) Calculates the ballistic coefficient for near and far velocities, atmospheric conditions and drag function. Now you simply cross-reference your OBV with your ballistic data to ascertain your maximum effective range. This calculator is used to find the optimal twist rate for your bullet. We thought you might enjoy it as well. This calculator is a simple estimator. Muzzle velocity is the velocity or speed at which bullet leaves from the gun. Power factor is calculated by the formula: bullet weight times velocity divided by 1000. Simple add the speed and grains into each of the boxes for each column. For very accurate results, remember to account for the velocity lost in the 10-15 feet between the muzzle and the chronograph. Our initial research data covered the relationship between barrel length and velocity for some 13 common handgun calibers/cartridges. Muzzle Velocity How fast the bullet leaves the rifle as measured by a chronograph. Ballistics Calculator Stability Calculator Bullet Comparator Velocity Estimator Recoil Calculator Hit Probability Calculator. Higher the muzzle velocity, better the chance of the bullet reaching the target quickly. Obtain multiple velocities from different gun settings or any other combination you want to compare with our FPE calculator to calculate muzzle energy. It is calculated from mass, velocity and weight of the bullet. Calculating Ammunition Power Factor. Click Here to open in small window. Enter the first two variables, then press calculate. Bullet Energy Calculator. Please Note the Muzzle Velocity Result as well as the Suggested Twist Rate. This reloading article provides a ballistic calculator that helps you compare different weight bullets, at any velocity, to see which one will hit harder. As a rule of thumb, a bullet looses 5-15 fps in this short distance. The Bison Ballistics calculator is a modern ballistics calculator for sportsmen. Bullet Database; Ballistics Calculator. Optimal Bullet Velocity Calculator Instructions: Simply, enter the weight of your target animal, the bullet weight in grains, and the OBV row will self populate and give you an Optimal Bullet Velocity. Bullet Drag and Twist Calculates the bullet CD, and CD components, BC required twist and stability for input twist. Muzzle Velocity Calculator. The Magneto Speed chronograph mounts to the muzzle, or the suppressor in this case, to measure the velocity of the bullet as it exits the rifle. We use this nifty bullet energy calculator when we chronograph projectiles. Muzzle energy is the kinetic energy of the bullet when expelled out from the muzzle to the target.
