Is 5.7x28mm just overpriced .22 Magnum?
No.
My question after the 22 Mag question is, what does 5.7 do better than 9mm in handguns or 5.56 in rifles?
I have much more faith in a 100+ grain pistol velocity cartridge against bone and ribcage than a 22LR, 22 Mag, or 5.7. I'm not convinced 5.7 has enough velocity in a pistol to be discussed like a rifle cartridge from a terminal standpoint.
It does nothing better than 9mm or 5.56 except one thing, low recoil. I would not use it in a handgun, but medical problems drove me to it in long guns where all the recoil I can tolerate is about rimfire levels, it is that.
22WMR is not as reliable nor durable as this centerfire cartridge in long guns, and my chrono says I am getting 2550 fps from a 10" barrel with LF198, no 22 WMR is getting that.
It is encouraging to see that Lucky Gunner seems to be using shear-validated 10% ordnance gelatin. It would be nice to see them depart from the use of the Clear Ballistics goo and actually do their customer base a useful service that would allow a valid comparison of ammunition in a valid test medium.
However, Chris Baker's (mis)use of terms like ''wound channel'' (3:23) suggests that he may be unaware of the fact that the attribution of damage that occurs in 10% ordnance gelatin does not necessarily correlate with that which might occur in living tissue due to the large difference in elastic yield strengths between gelatin and soft tissues.
Baker's statement with regard to the diameter of temporary cavity ''that really needs to be closer to about 4 inches before we can really rely on the temp cavity to have any immediate effect on the target'' (4:40) suggests a misunderstanding of the phenomena involved since most visceral tissues can sustain temporary cavities greater than 4 inches in diameter without damage.
Actually, I'm pretty sure he was saying the same thing you are. He was saying that those smaller stretch cavities will not permanently tear actual tissue. I've heard him say exactly what you're saying about flesh vs gel numerous times. I don't think he meant wound channel as in literal flesh wounding, just perhaps an unfortunate or confusing term for the damage in the gel
I think that you might be misunderstanding the point that I was making; I will clarify...
I reviewed the Lucky Gunner video again.
Baker's statement, taken word for word from the attached video, ''that really needs to be closer to about 4 inches before we can really rely on the temp cavity to have any immediate effect on the target'' suggests that a temporary cavity having a diameter of 4 inches is some sort of threshold for damage in human soft tissues. No such threshold exists. Many visceral tissues—pulmonary, upper and lower gastrointestinal, adipose, and muscle tissue, etc—exhibit no damage when subjected to temporary cavities that exceed 4 inches diameter. The idea that such a low threshold for soft tissue damage exists at just 4 inches of temporary cavity diameter is inaccurate and misleading.
As for Baker's use of the term ''wound channel'', his use of that term in this particular context carries with it the connotation that there is some sort of equivalence or correlation between that which is seen in the ordnance gelatin and in human soft tissues. I agree that his use of the term is unfortunate since it introduces the potential for further confusion into a topic that has seen too much of it already.
It can penetrate armor at a greater range than 9mm AP with less recoil and greater capacity, while fitting (rather, being viable) in smaller guns than 5.56 can.
Whether that matters to you and the context you use firearms is a variable, but that's the purpose of the round, why it was designed, and the answer to what it does better.
