[35], SS109/M855 NATO ball can penetrate up to 3 mm (0.12 in) of steel at 600 meters. [citation needed], U.S. Special Forces had sought to create a round that had increased power out of carbine M4 barrels and compact SCAR-L barrels, while increasing hard target performance.

ACME Machine’s entry into the 6.5 Grendel market utilizes a Ballistic Advantage barrel. [55], If the 5.56 mm bullet is moving too slowly to reliably yaw, expand, or fragment on impact, the wound size and potential to incapacitate a person is greatly reduced.

[62][63], In July 2012, the Army solicited a request for vendors to supply alternative cartridge cases to reduce the weight of an M855A1 5.56 mm round by at least 10 percent, as well as for the 7.62 NATO and .50 BMG rounds. Toll-Free: +1-800-504-5897 But testing showed chamber pressures to be excessively high. This fragmentation effect is highly dependent on velocity, and therefore barrel length: short-barreled carbines generate less muzzle velocity and therefore lose wounding effectiveness at much shorter ranges than longer-barreled rifles.
