With this in mind, a .45 ACP moving at approximately 800 fps is an ideal cartridge to use when conducting experiments with ricochets. Investigators in the field typically would not have the requisite information available to estimate a critical angle when a ricochet marking is discovered at a crime scene so field testing with a similar cartridge and the same or similar substrate would be a benefit to the CSI’s analysis when calculating the approximate critical angle is necessary.References:Hueske, Ed.
