Winchester Super X .357 Magnum 125 Gr WinClean BEB

The Winchester Super X WinClean .357 Magnum 125 Gr Brass Enclosed Base (BEB) is engineered for shooters who demand a cleaner, safer range experience without sacrificing performance. Built on Winchester's WinClean technology platform, this cartridge fully encloses the lead core in a brass jacket from tip to base — eliminating the lead vaporization that occurs at the bullet's base upon firing. Paired with Winchester's patented lead and heavy metal free primer, this round removes the primary sources of airborne lead exposure at the shooter's station, making it an excellent choice for both indoor and outdoor range use.
