Does SIZE Matter?...S&B Exergy .40 S&W Copper Self-Defense AMMO Ballistic Gel Test & Review!
This video provides a detailed ballistic gel test and review of the S&B Exergy .40 S&W 130-grain solid copper self-defense ammunition. The instructor, with extensive experience, tests the ammunition from two different barrel lengths (3.5-inch Glock 27 and 4.5-inch Glock 22) to assess velocity, expansion, and penetration. While the ammunition demonstrated good expansion and penetration, the instructor found the velocities, particularly from the shorter barrel, to be on the lower side for .40 S&W, suggesting it might be underloaded for his personal preference.
