We will call this ammo day at SHOT.
Hornady is offering a Critical defense load for the .22 Mag which would be a perfect match for short barrel revolvers or Kel-Tec’s new PMR 30, 30 round pistol.
Winchester has also expanded their PDX 1 line to include a .223 Remington load with a unique new bullet design called the Split Core bullet. It works similar to a Nosler Partition but the core essentially contains two different lead alloys; a soft one in the front and a hard one in the rear. This give you good tissue damage and deep penetration.
