I don’t quite understand the purpose of this experiment other than to say that they did it because there’s already countless other occurrences of the same situation and catastrophic results. However I always enjoy a good test video and unintended experimentation of modern day squeezebores (kidding).
That makes a very long 5.56mm bullet!
Makes a 6.5 Carcano look short. Maybe they should test out single loadings of the .30 SALVO next time?
