Put it to bed guys! The point is not a body count between FMJ and HP ammo, you may as well be counting musket balls and tell him to shoot lead for its "killed more men than any other" factor.
The point to consider is that hollow points were meant to inflict damage with controlled expansion. That expansion is two-fold in purpose: enlarge the wound channel and dump stored energy into the target. Why is that important? Anyone? To cause damage to the intended AND ONLY the intended. Carrying a pistol does not give you the right to use it in any manner you see fit. It also, most assuredly does not give you the right to inflict collateral damage to others who may be BEHIND your intended target. That is why the rangemaster does not allow people to wander down range when the line is hot. While you know you're aiming at your target, he doesn't know how good your aim is.
That being said, every cartridge has an intended purpose. Do not doubt or rethink its ability to "put a man down". Read what the manufacturer has to say about it beyond the ballistic chart. Hornady TAP for instance is meant for penetration...of mild steel. Hornady Critical Defense is meant for penetration of humans without clogging or deforming when it hits fabrics (like clothing, in case your assailant isn't nude).
Yes, a chronograph is helpful, even more so if you load your own. I've got one and have owned one for nearly two decades. They're cheap, accurate and can provide some peace of mind when determining whether or not a round will do what it is purported to.
Lastly, does anyone ever really think about what they post on the internet these days? Calling yourself "man killer" or "rightous angel" and asking what works best in your third back up mag will not likely remain anonymous if you jerk that pistol and shoot someone. One day at a police forensics lab and a prosecutor or "wrongful death" attorney will have you seeing bars and or your family eating at a soup kitchen. So practice a little restraint here, we are already characterized by the media as "gun totin thugs". Imagine if they did a nightly news story on some of the above postings.
Part II
Any of the aforementioned ammo should work fine for the majority of self-defense situations. Be conscious of your surroundings and what you're likely to encounter. If TAP is what you think you need then load a magazine with it. Keep another loaded with Winchester and keep a shotgun with a tactical light and #5 shot for home defense. You've put a lot of thought into one area and perhaps neglected a few others. I'm glad to see so many interested parties either way and I hope none of us ever has to find out first-hand about any ammo's stopping power.
Sorry in advance for the lecture, I simply worry that some day, given the odds, someone on here will overstep their bounds and become what they sought protection from. My personal choice is the Hornady XTP in 155gr and 5.5gr of TiteGroup in a Federal wrapper. I neither endorse said round nor recommend it as we do not know eachother and you have no reason to accept my recipe for your particular need.
Stay safe, shop smart, shop S Mart.
