10mm Auto vs .357 SIG

The 10mm Auto vs .357 SIG comparison pits two high-performance semi-automatic cartridges against each other. The 10mm Auto (175gr JHP at 1150 fps) uses a heavier bullet for 429 ft-lbs at 50 yards, while the .357 SIG (125gr JHP at 1350 fps) trades mass for velocity to produce 388 ft-lbs. Both achieve optimal FBI penetration depths: the 10mm reaches 15.5-15.9 inches and the .357 SIG hits 14.4-14.8 inches. Recoil runs similar with the 10mm at 7.69 ft-lbs and .357 SIG at 7.14 ft-lbs. The 10mm offers more versatility with load options from mild to full-power. Performance varies with ammunition selection and firearm platform.
