Does Winter Clothing Affect Your Self Defense Ammo?! (FMJ vs JHP)
This video details an experiment testing how winter clothing affects self-defense ammunition performance using ballistic gel. The host, demonstrating high expertise in ammunition testing, found that heavier clothing layers significantly hindered the expansion of most hollow-point rounds (.380 ACP, 9mm, .45 ACP), effectively turning them into full metal jacket-like projectiles with increased penetration. Only the high-velocity 10mm Auto reliably expanded through the simulated winter gear.
