Extended effective range. In match barrels, hits out to 600 yds. and beyond are possible.
Match Grade MOA or better accuracy is typical.
Extreme uniformity due to careful component selection and meticulous manufacture

Quality Components and Manufacture
ASYM PRECISION 77gr. Tactical OTM is loaded in virgin Lake City brass, which has been sorted and prepped for best performance and uniformity. Load specific loading techniques are used, which balance neck tension, crimp and the cannelured bullet for proper function in semi and full auto platforms, as well as bolt actions.

A high quality, clean burning powder is used, specially selected for its high velocity potential at safe operating pressures, and relative insensitivity to temperature. Powder charges are extremely consistent.

Best quality, Made in USA primers are used. The primers were carefully selected for their ideal cup thickness, sensitivity, uniformity, and brisance.

Relentless Quality Control
As with ALL ASYM PRECISION Ammunition, every round is chamber checked in a min. spec gauge and hand inspected for flawless performance. Ammunition is subjected to rigorous and frequent testing.
