The PDX1 Defender has a “notched,” or scored, jacket that peels back into deadly petals as it encounters resistance, but its lead core is bonded to the jacket. It averaged 971 fps, penetrated 19 papers, and expanded to .799 inch, effectively doubling its size. It retained 96 percent of its weight and had zero feeding issues. In dry newspapers, the jacket expanded rather wildly but did not separate from its core. It is the least expensive of the loads tested, at $21 for 20 rounds.
