By filling the open space behind a pre-scored, full-metal case with a polymer ball, Federal has created one of the most reliably feeding and expanding bullets available. By making these bullets in lightweight offerings, it has also created low-recoiling ammunition. The 105-grain 9 mm load is just one example. Penetration is, in my mind, an optimal 9.5 inches. That, combined with the high velocity and wide expansion, helps to create a wide wound cavity for this light-recoiling 9 mm personal-defense option.
| Load | MV (fps) | PEN (inches) | EXP (inches) | RW (grains) |
| 9 mm Federal 105-grain EFMJ/PDLR | 1,254 | 9.50 | .61 | 105 |
