Just thinking about these ammo threads made me take a mental trip down memory lane. Of course, the ol brain ain't what it was, so I was limited in my trip, lol.
I was pondering on the development of Super Vel, and it's impact on how we thought, or what we thought gave a bullet killing, or stopping power. New terminology developed such as " hydrostatic shock" and " shocking power", and became the new way we were told bullets killed.
Roy Weatherby had great success doing essentially the same with the lighter, faster loads of his new rifles.
The Speer " flying ashtray" was the order of the day for the 45acp. And even revolvers began to use lighter faster loadings to create that " fluid shockwave" effect that was the new science of the day.
This went on for quite a while. Then, it seemed like the pendulum began to swing again the other way. But the problems encountered were keeping the expansion while getting the penetration.
Now in the current day, great effort has been put into making bullets that give us both. But, people seem to be split into two schools of thought. Expansion if you can get it with the emphasis on penetration, or expansion primarily.
Looking back, I don't think the old Speer flying ashtray was that great of a round. And I'm not sure it was any real improvement over the round nose.
Additionally, while I believe in proper penetration over all things, when I think about the effects that absorbing all the energy of a 357 magnum of some 500-600 pounds of absorption impact, I can't help but to think that this gut jarring hit, can't help but have some influence on the body, that could shut it down. So therefor, even though I am a big bullet, penetration believer, I can't rule out the attributes of the fast step, impact of the lighter faster calibers.
Probably, the biggest problem I have with the latter is the what ifs of the what ifs....those damn variables.
Anyway, these are just some thoughts, not meant to be wrong or right, just thinking about where we have come from since the 70s and where we are now....and how we are still about as at odds with it now as back then.
So, I invite your thoughts, opinions or recollections from the past on this topic. I think it would be interesting to hear others perspectives, especially from those of you who can remember when it all got serious, and made gun rags and writers a ton of money!
