The most impressive info on the MagSafe site related to the "Strasbourg Tests":
The now -famous Strasbourg Tests put MagSafe on the map. To Summarize what nearly everyone already knows, over 600 live French Alpine goats (their bodies are very much like humans) were shot under controlled conditions: no anesthetic, same shot placement form animal to animal, and with blood pressure and heart rate monitors to determine the Incapacitation Time (measure of how long it took a goat to cease functioning after the single shot was delivered).You can read the full article here.MagSafe Ammo worked - better than anything else. Tests were done without MagSafe's knowledge, so some versions tested were the lowest powered. For example, two types of .380 ACP are offered; the .380 Defender, a 60-grainer at 1,360 fps in a Colt Mustang; and the .380 MAX (designed for a big city's undercover drug agents) with a 52-grain slug sizzling along at 1,620 fps in the Mustang.
The Defender has 247 ft-lbs of energy, while the MAX load has 303 ft-lbs. The Defender's lower velocity hampered stopping power, resulting in a Average Incapacitation Time (AIT) of 7.12 seconds. That's the average time for five different goats, each shot once with the MagSafe 60-grain Defender.
However - and this is where things get interesting - there wasn't a jacketed hollowpoint bullet in ANY caliber which dropped the goats faster than MagSafe's weakest .380 load!
They also mention gelatin tests where their rounds penetrate 10-12" of gelatin...far more than Glaser safety slugs for instance.
MagSafe seems to have a good engineering approach to their products from what I read.
I would like to read some real-world accounts of their use before buying any... :-)
BTW, looking around I did find this counterpoint article. While interesting, I note that it does not contain any actual testing to back up its conclusions.
If you take a look here:

you will find a great deal of technical info on bullets and the damage they do, as well as a great deal of controlled testing data.
There is also a pretty interesting FBI report on wound ballistics.
