Smart Shot, lead, steel and dust
By Dennis Adler
A pound of lead or a pound of Dust Devils will fall at the same rate of speed according to Galileo, but a 7.4 gr. lead BB will have a slower velocity than a 4.34 gr. Dust Devil. Galileo never had to deal with such problems. To begin our final installment let’s review the velocities with the test guns fired using Smart Shot and Dust Devils.
The first gun up was the latest Umarex Walther PPK/S which sent the heavy copper plated lead shots downrange at a marginal average velocity of 228 fps, and even with .177 caliber steel BBs the PPK/S can barley do better than 290 fps. But loading the Walther with Dust Devil BBs gave the CO2 pistol a competitive average velocity of 315 fps. So, let’s see what the PPK/S delivers in accuracy at that velocity, and not from 15 feet but a full 21 feet like other blowback action BB models that shoot in the 300 fps range.
