Terminal Effect SBR 556
Here’s a link to a small study of the effectiveness of 5.56 ammunition in gel at 10 and 83 yards. Conclusions? Based on this Limited performance test, 7” and 10.5” barrels still provide 100% expansion and beyond 12” of penetration, basically pistol like performance. They will not have the velocity to create the shock wave of the small high speed bullet From a longer barrel, but they have greater accuracy, capacity and range than a handgun.
