Maybe I "misunderstood" what you wrote because the title of your thread states you are laughing about hydrostatic shock effects. I haven't seen any claims of hydrostatic shock effects from Lehigh bullets.
I have seen claims and subsequent gel results that Lehigh bullets fluted flat nose design cut much larger wound channels than their diameter because of hydraulic action of that design.
Your supposition that there is no difference in the wounding effects and the disabling effects between FMJ and JHP or any other bullet shape in the outcome of a shooting is ludicrous.
The only merit I find in anything you have posted so far is the lack real world street results for the Lehigh XP and XD bullets, even in hunting applications. Short of those results, I wouldn't fault anyone for not wanting to use it as the last line of defense in SD settings.
I found Railsplitters logic of when and why he would use the rounds to be pretty sound.
Hydraulic wounding and hydrostatic shock are one in the same. Lehigh Defense claims these bullets wound using fluid. Hydro and Hydra both mean water. These bullet designs use hydraulics to wound. Gel will show fluid dispersment differently than it will occur in a human body.
Again, you aren't comprehending what I'm writing. I never said there is no difference in terminal performance between JHP and FMJ. I said it is difficult to determine exactly how much more effective JHP ammunition is than FMJ ammunition.
A bullet through the heart, lungs, major blood vessel, central nervous system will produce the same result regardless of its design. It will produce a wound through a viral organ that is both potentially fatal and potentially incapacitating wound.
Determining the difference between the two designs is difficult. In the past 25 years when JHP have become more reliable and more widespread in their use,firearms training has greatly improved which in turn has helped to produce more effective shot placement. Also, people are now trained to shoot much faster and until the threat stops or is down. This typically results in a lot more rounds fired than the old training to fire a double tap or hammer and then reasses the situation. More effective fire on target and more rounds on target.
People tend to forget that FMJ has been killing people for over 100 years on the battlefield. I've seen people take FMJ to the boiler room and have a lethal/incapacitating wound. Fellow officers have shot suspects multiple times in the upper chest with 180gr Ranger T and not recieved incapacitations. One fellow took 16 rounds to the chest. He died 5 mins later. Another took 4 rounds to the upper chest, ceased hostility and then fought officers going into custody.
I was personally involved in another incident. Suspect shot 4 times with premium JHP in the abdomen. I had to go hand to hand with him to disarm him from the taser he stole and place him in custody.
An FMJ is effective when placed properly, same as a JHP. A JHP is just as ineffective as an FMJ when placed improperly. The terminal effect of a JHP is not magical and won't produce much different results from an FMJ with the same placement. We carry JHP because it gives us a slight edge and we can use any edge we can get.
This Lehigh stuff is gimmicky. It's expensive and won't produce a much more dramatic wounding effect than an FMJ in the real world. You'll have a 35 caliber hole going in and a 35 caliber hole coming out. If you're going to carry these just save your money and buy some quality FMJ.
These bullets will most likely never have a large amount of street results. I don't anticipate any major LEA adopting these rounds for the above listed reasons. Civilian use in gun fights will be minimal because these things are expensive and typically people who can afford this stuff won't be in situations where they need it, generally.
If we accept that pistol cartridges produce significant enough velocity to produce hydraulic or hydrostatic effect, which I'm not sure to what extent is possible given the low velocities, we should most definitely not use a monolithic non-expanding bullet design.
These bullets are so specialized in their use I don't see a practical defensive application for them. An offensive application perhaps when barriers in a given environment are know, but even then in an offensive role long arms will be utilized long before pistols are.
