I continue to get email from last year’s “Self defense, stopping power, and caliber” series. It remains the second-most visited page on the site, behind only my article on lubrication, and appears to be well received by the majority of readers. Thank you!
As you might imagine, such popularity generates feedback, and some questions pop up more than once. While not exactly a FAQ, here are some of the common emails I’ve received.
Email: You didn’t cover the difference between crush and temporary cavities, which I think is very important.
My answer: No, I didn’t – because I don’t consider it critical to the discussion. You see, I really don’t care what the wounding mechanism is, as long as one exists. Going back to the article, as long as the bullet a) reaches something that the body finds immediately important, and b) does rapid and significant damage to that thing when it arrives, then I’m really unconcerned about how it actually does so. (The contribution of the temporary cavity to incapacitation is a subject of great debate even amongst projectile designers. At the layman level, it’s nothing more than bloviation.)
Email: Can you comment on ammo from [a smaller maker], whose stuff is just as good but doesn’t waste money on advertising?
My answer: In general, I recommend that one avoid “boutique ammunition.” The majority (if not all) of such ammo purveyors are simply loading bullets made by someone else, but without the knowledge of how to make those bullets perform their best. Why should I risk unknown quality control to get a product that, at best, can only be as good as what I can get from a producer that has actual design and test budgets? My advice is to stick with known quantities: Winchester, Speer, Federal, Remington.
Email: What’s your opinion of the book “Handgun Stopping Power” (aka “Street Stoppers”, aka ‘Marshall & Sanow’)?
My answer: There are a number of solid, critical analyses of their work online; I suggest that you read some of them, as the problems with their “research” are both serious and numerous. In case I was too subtle in the articles, I consider stopping power ratings in general to be complete hogwash, and theirs are particularly so.
You’d be further ahead to take the money you would have spent on their book, and practice until you can shoot to a high standard of accuracy under stress. Couple that with a quality hollowpoint from a major manufacturer, and you’ll be much better prepared than any ten people who swear by their scribblings.
(This should not be construed to mean that I am a follower of their chief antagonist, Dr. Martin Fackler, either. He concocted his ratings from a different sort of nonsense than Marshall & Sanow, and came to different conclusions – which were just as useless. Again, there is criticism of his work that can be found on the ‘net, if one is so inclined.)
Email: Is there any reliable source of information on bullet performance?
My answer: Because of the huge number of variables in any shooting, and the relatively low number of incidents, the idea of hard statistical data is meaningless. What we’re left with is anecdotal evidence which, while not valid in a scientific sense, does give us some rough feeling for what is and is not working. That’s the best we can do under the circumstances.
One of the more prolific collectors of such information is Massad Ayoob. He is in a unique position: since he travels all over the country both as a trainer and an expert witness, he’s thrown into contact with large numbers of police trainers and shooting survivors. He elicits their opinions of their issue ammunition, based on shootings in their departments. He gets some great feedback, which he doesn’t try to disguise or characterize as anything other than raw opinion from people who have actual results to talk about.
If you want to hear some of Ayoob’s findings direct from the man himself, listen to this episode of the ProArms podcast.
