Starman,
Your results are classic "examples of one," and are flawed in other ways, since obviously original bullet weight and muzzle velocity were not the same.
MD,
you yourself compared a 200NP to the 168TSX for penetration
their MVs and original weights are also not the same, should we consider it a flawed comparison?
Repeated bullet tests repeated in various kinds of media (including animals),....
I don't put much relevance in any of those other( non animal tissue) kinds of test media.
Since none of them accurately replicate the mechanical properties of animal tissue reaction to projectiles.
some of them give very misleading results.
But they sure are good for entertainment purposes and to easily impress the uneducated.
Ballistic GEL:
is often used to test bullets, but its actually a Non-Newtonian (shear thickening) media,
can you say animal tissue reacts with the same Newtonian properties?
For a start, blood itself reacts the exact opposite to the reaction one gets from ballistic gel,
blood gets less viscous(less resistant) when agitated while ballistic gel gets more viscous(more resistant) with agitation.
(to give people an idea of how important the Newtownian nature of a particular bullet test media is,
just consider that they are designing bullet proof vests with Non Newtonian-shear thickening fluids.
So its not something to ignore.)
Telephone book tests:
These tests make me laugh, simply because animal tissue does not at all react like wet paper to a rifle projectile.
Paper has very different shear and tensile properties to animal tissue. Wet paper also "wads -up" to form a
clump in front of a travelling projectile....as such it produces a larger frontal- larger wound channel and larger exit hole
in the paper than would be achieved with just a bullet passing through animal tissue.
We know that the greens found in an animals gut do (like paper)also wad-up and slow/stop a bullet considerably
So a sensible person would not use either of such type clumping-wading materials to simulate penetration of animal tissue
..or the common chest shot.
Water jug tests :
water is not like animal tissue because it does not compress.
Water is also not like blood or ballistic gel, because the Newtonian nature of water is that its viscosity does not change
with agitation.
Water is at best a good bullet trap.
