(18,606 posts)46. The 5.56 is not a good short range SD ammo
Angle-of-Attack (AOA) variations between different projectiles, even within the same lot of ammo, as well as Fleet Yaw variations between different rifles, were recently elucidated by the JSWB-IPT. These yaw issues were most noticeable at close ranges and were more prevalent with certain calibers and bullet stylesthe most susceptible being 5.56 mm FMJ ammunition like M855 and M193.
What this means is that two shooters firing the same lot of M855 from their M4s with identical shot placement can have dramatically different terminal performance results: one shooter states that his M855 is working great and is effective at dropping bad guys, while the other complains his opponents are not being incapacitated because M855 is zipping right through the targets without upsetting. Both shooters are telling the truth Gary Roberts, MD 2009
