Lehigh Defense Rifle Ammo Review

Lehigh Defense Rifle Ammo Review

FourGuysGuns threw together a couple of gel blocks, a high speed camera, a couple of Lehigh Defense's rounds and (regrettably) some techno music to demonstrate what a selection of Lehigh’s rifle ammo does upon impact.  In the video they test the following rounds:

Lehigh Defense 55 grain .223 Controlled Chaos Rifle Ammo:

The Controlled Chaos is a high velocity round with a hollow point projectile that is machined from solid brass and built to fragment upon impact.  It was developed by Lehigh Defense in response to requests from animal control agencies who were seeking high trauma rifle ammo with a reduced chance of over penetration.  These 55 grain bullets fly at over 3000 FPS and break up on impact maximizing energy transfer and the size of the wound cavity.

This ammo is also available in a 45 grain projectile version.


Lehigh Defense 110 grain .300 Blackout Controlled Chaos Rifle Ammo:

Just like its .223 counterpart, the 110 grain Controlled Chaos is machined from bar stock and fragments upon impact.  The .300 Blackout version travels at 2400 FPS and carries over 1400 ft. lbs. of energy.  All this leads to the base penetrating approximately 2 feet in gel while the fragments stop at around 10 inches.


Lehigh Defense 194 grain .300 Blackout Maximum Expansion Rifle Ammo:

Like the Controlled Chaos, the Maximum Expansion is features a hollow point bullet.  Unlike the Controlled Chaos, the Maximum Expansion bullet is built to stick together and expand in a way similar to that of a traditional hollow point.  This bullet is more than 75% heavier than its Controlled Chaos partner and travels much more slowly.  So much slower that it is in fact a subsonic round.  This slower and heavier bullet draws back penetration to approximately 16 inches and makes a single large permanent wound cavity as the bullet expands to over an inch in diameter.


Watch the video below to see how the three different rounds performed in the Doctor Kote Ballistics gel.
