"Let's make a realistic and fair comparison of the 22 Mag and the 38 Special when fired from a defensive handgun..."
To be fair, that intro should have been:
"Let's make a realistic and fair comparison of the 22 Mag and the 38 Special +P when fired from a defensive handgun..."
Heck I'm all for comparing a good ol' .38sp 158 grain wadcutter load against the .22M. Anyone game? But it ain't gonna change a dang thing. Anyone, and I mean anyone, who thinks a .22M is anywhere close to any .38sp load is off their rocker. There's numbers on paper and then there is real life. And cost for cast .38sp ammo is only fractionally higher.
To be fair, it's really hard to compare things if your just talking SD against 2 legged vermin. People, even bad guys, have a self awareness and a vast range of emotions that really screw with things when we talk effectiveness. Those in themselves change the playing field in comparisons between any cartridges.
So if you really want to see how bad the .38 trounces all over the .22M just go out and chest shoot some medium game like big coon, coyotes, even deer(if legal) or hogs. Only then can you really see what the difference is between the 2 and it's substantial to say the least.
