17 HMR Ballistics Chart Hornady Ammunition
Our 17 HMR Ammo Ballistics Chart will give you the bullet ballistic coefficient, muzzle energy, muzzle velocity and bullet drop of 17 hmr and 17 hmr2 cartridges.
Abbreviated by Manufacturer: (H) =Hornady
Lets compare the 17 HMR Hornady 20 gr Ballistics to the 17 HMR Hornady 15.5 gr Ballistics!
17 HMR Bullet Weight: Weight of the bullet in grains, there are 7000 grains in one pound. The abbreviation for grains is gr. There are 437.5 grains in one ounce. The bullet weight of 17 HMR Ammunition is 20 grains; therefore its bullet weight is .04 ounces. The bullet weight of 17 HMR Ammunition is 15.5 grains; therefore its bullet weight is .03 ounces.
17 HMR Ballistics Coefficient (BC): The ballistic coefficient of a bullet is the drag factor of a bullet. The number is in the form of a decimal. The higher the number, the lower the drag of the bullet. It's basically a measure of how streamlined the bullet is. The Bullet Ballistic Coefficient for 17 HMR Hornady 20 gr Ammo is .125 compared to the 17 HMR Hornady 15.5 gr Ammo with a BC of .115. The 17 HMR Hornady 20 gr Ammo has less drag than the 17 HMR Hornady 15.5 gr Ammo. Reference the Bullet Ballistic Coefficient Chart above.
17 HMR Muzzle Velocity: 17 HMR muzzle velocity is the speed with which a bullet leaves the barrel measured in feet per second (FPS). As a rule, the faster the muzzle velocity the shorter the bullets time in flight, and therefore a flatter trajectory and less drop. The muzzle velocity of the 17 HMR Hornady 20 gr Ammo is 2,375 fps compared to the 2,525 fps of the 17 HMR Hornady 15.5 gr Ammo. If you look at the 17 HMR ballistics table above you will see how the muzzle velocity of 17 HMR diminishes at 100 yards and 200 yards.
17 HMR Muzzle Energy: 17 HMR muzzle energy is measured in foot pounds to determine the destructive potential of the bullet. The 17 HMR muzzle energy is the kinetic energy of the bullet as it leaves the muzzle. Generally, the heavier and faster the bullet, the more damage it will do to the intended target. As you can see, the 17 HMR Hornady 20 gr Ammo has a higher muzzle energy from zero to 200 yards in comparison to the 17 HMR Hornady 15.5 gr Ammo. The 20 grain 17 HMR has a much higher kinetic energy, which translates to more killing power at distance. Look at the 17 HMR ballistics table to compare the muzzle energy at various distances.
17 HMR Bullet Drop Chart: Shows how 17 HMR Ballistics and 17 HMR2 Ballistics compare to one another in the bullet drop comparison at various distances. With a rifle zeroed at 50 yards this 17 HMR bullet drop chart shows how each cartridge compares at distances of 75 yards, 100 yards, 150 yards and 200 yards. If you want to see a visual take a look at the 17 HMR & 17 HMR2 Bullet Trajectory Chart!
