Army Research Labs recently subjected several new fabrics to ballistic testing to see how they might perform in protecting against explosively launched debris for applications in clothing and other gear such as Protective Under Garments. They chose airsoft BBs from BB Bastard as test projectiles because they replicate the size and weight of gravel particles.
The report is quite interesting for those of us interested in materials, ballistic or for those who want a peek into what testing actually entails.
