This definitely seems like it's thinking along the same lines as the Lehigh rounds, especially with the "hydrodynamic ram effect" Polycase mentions... Interesting concept, especially given the construction of the rounds using what amounts to brazing alloy... I wonder how well these will hold up under such high velocities given the relatively low maximum working temperature of typical cupro phosphorus alloys. I wonder how favorably these compare to solid copper versus an alloy. Perhaps they have a special formula that makes them harder and/or less susceptible to extreme heat (especially when hitting hard barriers). This could definitely make for a unique pull down, regardless!
Hmmm looks to me like it starts tumbling almost immediately... I didn't notice hardly any of the "hydrodynamic ram" effect they mentioned. And for that matter: how does overall penetration look, especially considering it's incredibly light weight??
This also is a bare gel test. I asked where the four layer of Denim test is.
Valid point! I hadn't thought of that the entire video. I suspect highly that the denim won't be very kind to this round especially given the rather unique shape/design/function of the tip of the round. It would be interesting to see how it performed if it were just a tad bit heavier, perhaps made entirely out of copper?? Although, in truth, I think Lehigh has probably already done that ;)
That HUGE expansion envelope you see that expands behind the bullet is that Hydrodynamic Ram effect. In this case the envelope is Greatly increased in size over a standard bullet.
