Spark Range Tests
Understanding the flight behavior of 5.56mm SRTASpark range tests were conducted on 0.50 cal scaled-up model– at CDN Defence Research & Development Centre Valcartier
" key holing" at 25m is due to a high Magnus dynamic instabilityMax range requirement met because the projectile experiences high Magnus dynamic instability at all Mach numbers, causing yaw to increase in flight

5.56mm FX® Design Criteria
Objective: No penetration into human tissue
Means: Limit impact energy density of hits:Control muzzle velocity & projectile impact area
Tests by Sellier & Kneubuel show the energy bare human skin can absorb before breaking is approx. 0.1 J/mm2
Data generated by USAF Joint Non-Lethal Weapons, Human Effects Center of Excellence indicates that the maximum energy level the skin can absorb without penetration is 0.26 J/mm2
Energy Density = KE / Area = ½ mVi2 / ¼πdi
2
Where M = projectile mass, Vi = impact velocity and di = projectile impact diameter
