Threads on ballistics and stopping power/energy transfer/ energy dump/ momentum/velocity are very interesting., but here is what it boils down to and here is what I have learned from threads like these. I have read about a 1000 similar threads on forums like this. My summary of what I have learned.
1. There are about 1,000,000 variables in a defensive shooting situation. They cannot be quantified even by an experienced physicist.
2. Carry the highest and most effective caliber chambering that you can shoot proficiently.
3. Hope to God that you will never have to test these theories in an ACTUAL tactical situation.
4. Take up reloading and learn more about projectile ballistics.
5. An expert, even with a PHD after their name is not necessarily someone who knows ballistics or a gun person. Understanding how projectiles behave while moving is not the same as understanding ballistics as it pertains to firearms.
6. Never say that a .40SW or a .45ACP is superior to a 9mm ,because superior is a relative term dependant on shot placement and I sure as hell dont want to get hit with any 9mm center mass.
7. Never say that a cartridge has to begin with the number 4 to be effective. I am not ready to give up my .357MAG or 10mm just yet. If you say that a cartridge has to begin with the number 4 to be effective to an experienced shooter, they will look at you like you are a martian.
8. Repeat #5.
9. Shooting test against watermelons and water are great but do not simulate the human cranium as it pertains to penetrating bone. Head shots are more difficult because they are a smaller target and one should aim center mass if possible. Even centermass shots have to deal with bone and dense muscle tissue. Gelatin and watermelons ARE NOT THE HUMAN BODY.
10. feedback welcome.
