  • Hydrostatic Shock

    Any thoughts on the phenomenon of hydrostatic shock? I don't know enough about rifle-shooting to have an opinion. Always found it interesting, though. I remember reading about it when I was a kid in an article about snipers.

    I did not read the article yet but the first thing we were taught as a medic for GSW was control hemmorage and second TREAT FOR SHOCK. Shock wan kill just as quick as loss of blood.

    Think of it this way - suppose you, without warning are scrred out of your skin. Substitute shocked for scarred. That effect your body feels when scarred is similar how it would feel if hit with a bullet. Without treatment the body organs start to shut down one by one until it's lights out Click image for larger version

      Jim, that's a cool photo!

      Apparently, hydrostatic shock can happen but not consistently. Here's an interesting article:

      Hydrostatic shock | Military Wiki | Fandom (wikia.org)

      "Whereas virtually all of our opinions about knockdown power are based on isolated examples, the data gathered during the culling operation was taken from a number of animals. Even more important, the animals were then examined and dissected in a scientific manner by professionals.

      "Predictably, some of the buffalo dropped where they were shot and some didn't, even though all received near-identical hits in the vital heart-lung area. When the brains of all the buffalo were removed, the researchers discovered that those that had been knocked down instantly had suffered massive rupturing of blood vessels in the brain. The brains of animals that hadn't fallen instantly showed no such damage.

        Small, fast projectiles induce massive hydrostatic shock.
        I've seen deer killed with a .22-250.
        Single, good clean shoulder shot.
        That deer was blood shot from flank to ears.
        Deer hanging next to it was shot with a .50 muzzleloader.
        Blood shot spot was about 4" across!

          Noticed the difference in that between Barnes bullets and hornady sst.

            I never shot a bear when it was moving. If you do they take off like a jet. Usually a good shot on a standing bear is about a bang flop. Pic is my Military Passport.

              I think that's why the .25-06 is so devastating.
              It's the right bullet and right speed combo.

                I should have elaborated. The sst in my .270 would make a softball maybe a little bigger spot. The Barnes from my 25-06 maybe a silver dollar size. Both of them put 2 holes in deer. But the hornady sst probably transfer more energy. Judging by the size of blood shoot meat. Both do the same job just as effective for me I actually hunt. I could hunt with a 30-30 and iron sights. Haven’t shot a deer over 80 yards in a long time.

                  Where’s Clay Cooper when you need him?
                  He’ll tell you all about how awesome a .22-250 is on deer.

                  Seem to recall a story where someone killed a deer by accidentally hitting it in the foot but can’t remember who posted it.


                  A few things about the study, the deer hit with hard bullets only traveled on average 20 some yards father than soft ones. That’s not really saying much. It also doesn’t take into account shot placement, obviously central nervous system hits are more likely to put them down right there regardless of bullet used. It’s also interesting that the take away was that standard bullets are a better balance than hard ones.

                  I don’t doubt the results but I still want exit wounds. One of the bigger bucks I’ve killed was my first, using a .243 with a cup and core bullet. The shot was completely broadside mid shoulder at about 35 yards. Bullet didn’t exit and the buck didn’t drop. The way he hunched at the shot I knew he was hit hard but I didn’t get any real blood for about 50 yards. Found him about another 30-40 yards later.

                  That turned out ok but had similar experiences with that rifle and other deer. High shoulder shots put them down right there but lung hits they’d still run a bit. That’s the main reason I have my daughter using Partitions in her .243. Best of both worlds.

                    The last 3 deer I've killed was a high shoulder shot that disrupted the spine between the shoulder blades. D.I.R.T.

                    Two pass thru shots.
                    One entry wound only.

                      I’m a shoulder shooter myself grew up using slugs. It’s hard for them to run if you take out the running gear. And if you if hit bone it shrapnels everywhere bonus. All things being considered shot placement is most important but I’m am by no means no expert just a guy that likes to hunt.

                        For a "guy who just like to hunt" (most of us here! LOL!), you're about as spot on as any "hunter" can be.

                        I get wrankled at those that say, "I shoot at the big part!". What idiots!
                        Thankfully, I have not heard that one in a LONG time.

                            6.8?

                            I killed a decent 8pt with a 240gr XTP bullet pushed with 80gr of Pyrodex. Hit high shoulder/spine, the jacket separated and exited higher up on the entrance side. Found the lead under the hide on the opposite shoulder. Bang flop. Not exactly a high stepping combination.


                            Bigger deer I’ll try to break down with the shoulder but to save meat I look for lungs only on smaller ones. Don’t always get to choose though.

                              Dadgummit! No!
                              Two nice bucks with my (wife's) Ruger No.1 .270 Win and a doe with my T/C Omega Z5 .50 cal.
                              I've only taken one deer with my 6.8 as much as I go on about it.
                              I DID take 4 pigs with the 6.8 with no "runners".
