Water is not a suitable test medium for the performance of these bullets. Think about it this way. How far does the bullet penetrate in water compared to gelatin. 3-5 times farther or so, maybe more? Why? Water is less dense. Also, it also has no form. While a projectile's velocity increases meet with exponentially increased resistance as in elastic tissue, there is no resistance to the water flowing out of the path of the bullet. For these two reasons, shooting at water, or containers full of it, is fun, but is not a predictor of terminal performance. A third reason is that in tissue, because of the different media involved, increases in volocity do yield deeper penetration on average. In water, the faster you shoot, the less penetration you will get. (With the same bullet) This 3rd difference is the reason why tissue received both a temporary and permanent wound cavity. A mass of water, in a container large enough to contain the force, would display only a temorary cavity, visible only with a high speed camera.
For their intended purpose, these bullets are fine. Underneath that red tip is a cavernous hollow point that is pretty much impervious to plugging due to the rubber expansion point. On a target with more density, IE, MEAT, the results would be far better.
Also keep in mind that this is a controlled expansion bullet. Its not for self defense (two legged critters), but for hunting game with thick hides and tough bones protecting large and relatively resilient organs. The idea with this bullet is to allow it to penetrate the hide and THEN cause damage to the vitals through expansion, mechanican damage and energy transfer (If you believe in that). I am impressed that there was slight deformation on water alone, with no loss of mass.
In my mind, these make the ideal hunting or wilderness defense factory load for the Ranch Hand.
That is the reason that this ammunition is not marketed as personal defense ammo. Its not.
And I would even bet that a proven bullet like a Speer gold dot or Hornady XTP in any caliber would not show good results having been fired into a drum of water.
A really good test of this would be to fire a 17hmr into a drum of water. That bullet will upset on anything. I bet that at the very least you would find large pieces of the bullet at the bottom of the drum. It may even hold together. My guess is that the tip will come off that the bullet will upset only a little, as with the lever evolution ammo.
Anyone want to prove me wrong? I dont have a drum here. Or a wall to drag to the range and hide behind.
Maybe we can borrow the RCMP's. Oh wait. They dont use that ridiculous setup either.
OK, sorry, I am just being synical now. But I am curious about the .17.
