After watching the videos that I have found and the videos that JeeperCreeper provided for my post on Lehigh Bullets. What my take was with the fluted bullets is that the hydrostatic damage the Lehigh fluted bullets displayed in gel is may times deeper, producing a larger, longer major wound channe than any other design of bullet that is on the market now.
That has to be proven in real life experience as of yet, but that is there claim.
The fact that they are all copper, so they are light and go very fast, and the fact that they tend to throw shock sideways from the flutes doing a lot more hydrostatic damage much deeper into the target body because the nose design doesn't deform on impact, they think they have something that is superior to what's on the market now.
That's what they claim and their gel tests show.
Hydrostatic shock damage does a lot of damage aside from what the sensible damage of the bullet does. That comes from the speed and the nose design.
But I understand that hydrostatic shock only occurs if the bullet is traveling faster than the speed of sound of the material you are shooting it into.
A body has a lot faster speed of sound than air has because of being denser so these bullets aren't going fast enough to make hydrostatic shock by their fps but the nose design is suppose to make up for the deficit of speed.
The gel test seem to show this but they are new and gel isn't a final word on anything except what the FBI penetration standard is quantified by.
But hell, what do I know, just my take on it.
I'm going to do some playing with them but I'm interested in longer distance accuracy than 7 yards. I just ordered some Underwood factory ammo, the Lehigh Penetrator and Defense because I want to see for myself for the accuracy.
I'm not buying ballistic gel and test them, it's to expensive for me. On paper anyways these bullets look to be a better or at least different design that may prove to be something better after they have been put through the riggers of real life experience.
But they may prove to be illegal also, the Extreme Penetrators went through some kind of bullet proof vest and still penetrated 16-18" in gell in one of the videos. Who knows.
