PMC's 170-grain JHP brings an intriguing twist to the 10mm Auto platform. Rather than following the crowd with a 180-grain bullet, this load shaves off 10 grains to achieve a zippy 1200 fps velocity. That speed advantage, combined with 543 ft-lbs of muzzle energy, creates a defensive round that strikes fast and hits hard. The lighter projectile weight might raise questions among traditional 10mm shooters, but physics tells an interesting story about this round's capabilities.

When it comes to defensive scenarios, this load's jacketed hollow point design capitalizes on its increased velocity. The faster impact speed promotes reliable expansion, even through heavy clothing or at extended handgun ranges. That expansion potential, paired with the round's substantial energy, creates significant tissue disruption without excessive over-penetration risks. It's particularly relevant for urban defenders who need to balance stopping power with environmental awareness.

The lighter bullet weight pays dividends in the recoil department, especially during rapid follow-up shots. You'll notice the difference most during defensive drills requiring multiple target transitions or when engaging threats on the move. While some might dismiss it as too light for bear defense, its speed advantage actually helps ensure reliable expansion against tough hide and muscle - though you'd certainly want it as a backup rather than primary option in grizzly country. For those who value quick target reacquisition without sacrificing terminal performance, this load deserves serious consideration.
