Heavy vs Light...Is Either One "Just Right?" Underwood .357 Sig Self-Defense AMMO Test!
This video presents a ballistic test of two Underwood .357 Sig self-defense ammunition loads: a 115-grain Nosler ASP and a 147-grain Hornady XTP. The test involves firing rounds through a heavy clothing barrier into ballistic gel to evaluate velocity, expansion, fragmentation, and penetration. The presenter, experienced in firearms testing, notes that while both rounds performed adequately, neither weight (115gr or 147gr) is his preferred choice for .357 Sig, favoring a 125-grain projectile for this caliber.
