A system and a method of testing a specimen. The system includes an endcap, a plurality of bars, a plurality of strain gauges, and a gas gun. The endcap includes a first surface and a second surface opposite to the first surface. The first surface is curved. Each bar is disposed in contact with the second surface of the endcap and extends along a longitudinal axis. Each strain gauge is disposed on a surface of a corresponding bar from the plurality of bars. At least one strain gauge is disposed on the surface of each bar. The gas gun is configured to fire a specimen towards the first surface of the endcap such that the specimen impacts the first surface at an oblique angle relative to the longitudinal axis.
