Product Overview
Underwood Ammo 6.5mm Grendel fires the 110-grain Controlled Chaos bullet at 2,800 fps—the highest velocity in the Grendel lineup—generating 1,915 ft-lbs of muzzle energy. The Controlled Chaos is a Lehigh Defense projectile featuring a solid copper body machined to fragment in a specific pattern on impact. The G1 ballistic coefficient of 0.450 provides good aerodynamic performance despite the complex bullet design.
The Controlled Chaos operates differently than conventional expanding bullets. The nose section fragments into multiple wound channels while the solid copper base continues penetrating in a straight line. This creates both immediate tissue disruption from fragments and deep penetration from the retained base. Underwood loads this bullet to maximum safe pressure, extracting every foot-per-second the Grendel case can deliver. The result is terminal performance that exceeds what the cartridge typically produces.
Hog hunting and predator control are ideal applications where rapid incapacitation matters. The fragmenting nose creates immediate effect while the penetrating base ensures the bullet reaches vitals even on tough-skinned game. Hunters who prioritize stopping power within 200 yards will find this load hits harder than standard expanding bullets while still meeting lead-free requirements.
- At 2,800 fps, this is the fastest 6.5 Grendel load available, maximizing the cartridge's terminal potential
- Controlled Chaos design creates multiple wound channels from fragments while the base penetrates deeply
- Lead-free solid copper construction meets hunting regulations in California and other restricted states
- Underwood's hot loading philosophy extracts maximum performance from factory ammunition
- Maximum pressure loads may cause extraction issues in rifles with tight chambers or weak extractors
- Premium Lehigh bullets and hot loading push the per-round cost well above standard hunting ammunition
- The fragmenting design works best inside 200 yards—at longer ranges, reduced velocity may affect performance
- Underwood is a smaller manufacturer, so availability can be limited compared to major brands
