    Radially Dynamic Bullets?

    So the RIP ammo thread made me remember these things. i first saw them at least a few years ago. i like that at least their data is presented in a little more palatable manner...

    so what do ya'll think? i know nothing about these except what i've read here, seems ok in theory, but we all know what that means....

    Nasty. Wonder how they'd feed....the THV's. The Devel.....357 dynamics in a 45 ACP. Interesting.

    One fault in the design. Service pistol velocities are not high enough to cause TC tearing now matter what the bullet shape is.

    i've seen you post about this more than once now, i am curious, is this an accross the board fact? meaning; muscle is much "tougher" than say, veins and arteries. cartelidge is "tougher" than muscle. But that same "stiffness" of cartelidge means it will be easier to "disrupt". (hardness vs. elasticity)

    as my understanding of temporary wound cavities goes(and i could be completely wrong, that's why i'm asking) it is bruising, rapid bruising. i have heard it called "hydrostatic shock".

    i have heard that hydrostatic shock may cause temporary paralysis if the spinal cord is "bruised" during one of these events.

    So violent destruction of tissue it is not, requireing surgical repair, it does not.

    but i wonder if temporary cavities may have more effect than you are giving them credit for.

    Now, i am not arguing with you, i do not know these things as an expert. i am asking if you can validate your claims and perhaps provide some documentation?

    again, not arguing but would like to be better informed.

    The hard part about coming up with good wound data is getting enough info to make a viable study. Accepted terminal ballistic logic states that you will not see hydrostatic shock until you reach long barreled magnum velocity, I.E. .357 mag out of a 6" or longer barrel. The faster the bullet is moving, the more disruption it will cause; but keep in mind that velocity is only part of the equation. Bullet weight and size/shape also factor in... As do inertia, and energy. All of this together makes it difficult to quantify the effects of temporary cavity. If you get a CNS or vital (heart) hit, TC becomes moot. Another school of thought posits that TC is a result of bullet shape, and has little to do with velocity. So, caveat emptor, so to speak...

    This is about the best summary (key word) of terminal ballistics I was able to find...

    ^^^This is widely supported by many independent empirical sources.
    Temporary wound cavities become relevant as you cross the 2,000+ fps mv range. It is dependent upon many variables, but that is a start (not an absolute line, just a starting point)

    The words "radical" and "dynamic" are (when used standing alone) neither technical or scientific terms. In this example, they are MARKETING terms intended to sound like engineering validity. It might as well be "new" and "improved". Me? I give "zombie killer" much more credence.

    not arguing with your attack of marketing gimmicks, but it was RADIALLY DYNAMIC, not RADICAL. which *might* be proper engineering lingo.

    Thanks Kavalander, appreciate your literal admonishment. But remember, I actually READ (most of) your record-setting, long-winded, magniloquent, verbose, erudite posts. I trust you'll now equally appreciate my proof-reading skills. En garde!
