John Parker from Shooting Sports USA provides a first look at the Labradar LX portable ballistic chronograph. This compact device utilizes Doppler radar technology, similar to its larger predecessor, to measure projectile velocities and calculate standard ballistic data including average, minimum, maximum velocity, standard deviation, and extreme spread. It also features a power factor calculator, beneficial for action shooting sports like USPSA and IDPA. The LX boasts an 8-hour internal battery, an arm button for power saving, and distinct modes for rifle, pistol, and bows, with a companion smartphone app for ease of use.
This video provides a direct comparison between 7.62x39mm and 5.56mm/.223 Remington calibers using ballistic gel-filled chickens. The expert instructor demonstrates the terminal ballistics of Hornady SST bullets from both a KS-47 (7.62x39) and a Stag Arms AR-15 (5.56mm), detailing the impact and fragmentation differences. The analysis highlights the more destructive performance of the 7.62x39mm round in this specific test scenario.
