NOTES ON ANIMATION

The animation is a simulation of a sub 12 ft/lb air rifle pellet moving from muzzle through 10 ‘ghost’ targets that offer no resistance. The LOS ‘line of sight’ is shown; that is the grey cross in the center. This represents the center of the reticle when viewed through the scope. The gun is fired such that the line of sight is directed at the center of the target and all the targets are in line. The pellet starts beneath the LOS then moves above it, gradually descending beneath the LOS over the course of 40 meters. This shows the hold compensation of a typical .22 air rifle. These hold contributions are written on the bottom left of the animation but you may have to pause it to re-read this data. Everything is to scale including the targets, pellet and rifle. The trajectory is based on real data.

The lasers are calibrated so that they form a single dot at the Maximum Ordinate range, ‘the highest point range’ or zenith of the trajectory. It shows how different in size the laser patterns appear on the targets at different ranges and how easy this change is to see. The lasers would be similar to this, if setup in this way using the Trilase in real life.

You can change the playback speed if you find the animation too slow; just turn off the sound and adjust the playback speed clicking the three dots both on the bottom right. You also have the option to see it full screen click the square icon on the bottom right.
