In this video, we test the dynamometer, which measures impact force, by comparing Grimburg JUL v3 projectiles versus Less Lethal Ballistics Smasher XL. Using the Pistelle X-68, the dynamometer showed that the Smasher XL hit with more 30% more force while the visual evidence of damage to the target discs was harder to discern. Conclusion: the dynamometer readings are much better at discerning actual impact force than visual evidence of target damage.
