New Winchester 10mm Pistol Loads Now Shipping

EAST ALTON, Ill. (June 24, 2019)— Winchester Ammunition is excited to announce two new ammunition options for 10mm pistol fans.  A full metal jacket and Defender® offering join an existing Silvertip® Hollow Point to provide an excellent variety of 10mm bullets for any need.
The 2019 additions include a 180-grain flat-nose FMJ in the white box Made in USA brand.  This is the perfect cartridge for practice or competition, offering both superb performance and a great value. 

The 10mm Defender is a 180-grain bonded projectile, ideal for self-defense and hunting.  The proprietary bonding process welds the jacket to the lead core resulting in consistent penetration and increased weight retention.  This bullet design, originally developed for the FBI, was engineered to pass their rigorous testing protocol requiring ammunition to consistently and reliably perform in varying situations.
