Our 357 Magnum ammunition is designed to hit hard, penetrate deep and shed petals during expansion.  The loss of petals allows for additional wound paths increasing the likelihood of striking a nearby blood vessel, organ or central nervous system all while reducing the core weight to protect against the danger of over-penetration.  The central core should expand to 150% of the original diameter, retain 75% or more of the projectile’s weight and penetrate not less than 18 inches of ballistic medium.

At Atomic Ammunition we know that you carry and use real guns, not test barrels.  All of our external ballistic information is obtained from tests using common firearms that you are likely to own and use, not inflated, misleading information from test barrels.  We feel that this is the most accurate and useful information for our customers, so it is the only information that we provide.
