The Hornady Handgun Hunter MonoFlex 10mm Auto 135 gr load delivers a hunter-focused cartridge that blends reliable terminal performance and tough construction for handgun hunting and field work, and if you run a hard-charging carry or woods rig this round answers the call. With Hornadys MonoFlex bullet design offering roughly 95% weight retention and an elastomer-filled cavity that promotes rapid, controlled expansion at a wide range of velocities, this ammunition yields deep penetration and consistent wound channels on heavy-bodied game and in dense cover where penetration matters most. Rated at about 1315 fps and roughly 518 ft-lbs of muzzle energy from a standard test barrel, the 135-grain MonoFlex in brass-cased, corrosion-resistant cartridges gives predictable point-of-impact with shooting platforms from full-size 10mm pistols to carbines. Made in the United States with attention to field performance and shipped under HazAir/ORM-D handling standards, Hornadys Handgun Hunter series is a go-to choice for hunters, guides, and experienced shooters wanting a hunting-specific 10mm load that balances expansion, weight retention, and penetration without sacrificing reliable feeding or accuracy in demanding conditions.
