This load was designed out of a customer request for a high-performance barrier-defeating 5.56 round with excellent terminal performance from a 10.5" barrel. Red Mountain Arsenal's load development program led to the creation of a 5.56 with a Lehigh Controlled Chaos solid copper round.
The load is extremely consistent and performs very well through glass and sheet metal barriers.
Terminal performance of the round is very good. The Lehigh bullet fragmented beautifully into 9" of ballistics get after passing through automotive glass. The solid copper bullet performed even after passing through sheet metal, penetrating all 18" of gel with several of the round's "petals" fragmenting within the gel.
Performance from an 18" barrel using a LabRadar chrono:
Velocity: 2,952.2 fps
Standard Dev: 9.64 fps
Extreme Spread: 30 fps
Group Size: 1.7" 10rd group @ 200yds or a little over ~2.3" if an 11th flier is counted - measured with an E-target.
