HRNDY 10MM 155GR XTP 20/200

Description

Hornady’s Custom line exists for shooters who want factory ammunition loaded to a standard that actually takes the cartridge seriously. This 10mm Auto load is built around the XTP — Extreme Terminal Performance — bullet, a jacketed hollow point designed to expand reliably across a wide range of impact velocities. That matters in 10mm because the cartridge generates enough energy that a bullet can arrive faster than some hollow points are engineered to handle; the XTP’s controlled-expansion jacket is designed to manage that and still drive deep rather than blowing apart on the surface.

At 155 grains, this projectile sits on the lighter end of the 10mm weight spectrum. The trade-off is straightforward: a lighter bullet at higher velocity produces a flatter trajectory and more energy at the muzzle, while heavier bullets in the same caliber tend to carry that energy further downrange with less velocity loss. For defensive use at realistic distances, the 155-grain XTP at 1,410 fps delivers 684 ft-lbs of muzzle energy — enough to make the case for 10mm as a serious option against both human threats and medium-sized animals. Brass cases are reloadable for those who work up their own loads and want to study how factory performance benchmarks against their hand loads. Each box contains 20 rounds.
