#MUZZLE VELOCITY CALCULATOR HOW TO#
Now you know how to measure the muzzle velocity of a gun. 22LR is considered to be a higher velocity bullet which is proven in the above-mentioned experiment. 954 FPSĪverage Muzzle Velocity: 299.96 MPS i.e. The results are as follows:Īverage Muzzle Velocity: 290.8 MPS i.e. The muzzle velocity measurement unit was MPS. This time we used two different kinds of bullets, ELEY Sports. We conducted another test to determine the muzzle velocity of IOF. We did another experiment, this time with a firearm. So, we have determined the average muzzle velocity of the Precihole VX100 Spartan air rifle. We fired 8 shots with RWS R10 Match Rifle 4.50 mm 8.2 grain air pellets. 177 Cal spring piston break barrel air rifle. We conducted a test to determine the muzzle velocity of Precihole VX100 Spartan. Muzzle Velocity of Precihole VX100 Spartan Thus, it is always recommended to collect multiple shot data to calculate the average value.
Please note that during firing a firearm or air gun, multiple factors can affect the muzzle velocity. Make sure you fire at least 5 – 6 shots and collect the reading on the display. Wellshot IR Velocimeter is capable to record 20 sets of shot data in its memory. The velocity will be displayed on the screen each time you fire. Once everything is set, fire your weapon through the chronograph channel. So, pay extra attention while setting up everything. bullet or pellet) may hit the chronograph itself and damage it. Moreover, if the inclination is high then the projectile (i.e. If the barrel is inclined upward or downward can cause incorrect results. In either weapon, make sure that the barrel is parallel to the ground level. If you are using an air gun, set the chronograph about 15 – 20 inches away from the muzzle. If you are using a firearm (especially a rifle), to avoid muzzle blast interference, set your chronograph at least 10 feet from the end of the muzzle. Once the chronograph is ready to use, place it a little away from the muzzle of your gun. Here is an easy video about unboxing and installing a Wellshot IR Velocimeter. It can measure the muzzle velocity in MPS as well as FPS.
Set your desired measuring unit accordingly. There are ballistic chronographs available in the market which are capable to measure the muzzle velocity in multiple units.
Set up your ballistic chronograph and mount it on a tripod if required.
Get to a shooting range with the above-mentioned equipment. A ballistic chronograph (We used Wellshot IR Velocimeter).5 – 6 Bullets (pellets in case of air gun).To measure the muzzle velocity, you need to have the followings: On contrary, in air guns, the kinetic energy is stored in the compression chamber. In the case of firearms, muzzle velocity mostly depends upon the bullet which is being used as the kinetic energy stored within the bullet shell in form of gun powder. Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots, or shell) with respect to the muzzle at the moment it leaves the end of a gun’s barrel (i.e.
