Is the FBI stupid? Hmmmmm ....
I'm not experienced enough with 30-06, have not shot one since I was a kid. What makes me think the .45 is "magic"?
What makes you use the word "magic"? What makes me think the .45 is capable of staggering or knocking down an average-sized guy in body armor is actual hands-on regular practice shooting them along with other caliber guns, and close friendships with guys who aren't amateur hobbyists who read FBI memos like yourself, but guys who actually pay their bills and mortgages and put their kids through school with money they earn because of their specialized, proven knowledge of firearms.
When is the last time you shot at a steel target, and how many rounds did you shoot?
I don’t shoot steel targets. Normally.
I have on occasion shot things like 50 gallon drums, and they didn’t rock back and forth. But then, they weighed more than 4 ounces...
I’ve shot rocks that weighed a few pounds, and they don’t go flying thru the air. I shot an injured dog in the head with a 38, and the bullet didn’t even come out the other side. The dog didn’t fly thru the air, either.
Cops do NOT make their living knowing guns. Most are lucky not to shoot themselves. And most former special forces guys...were never in the military.
Since you say you shoot a lot, go out sometime with a 20 lb weight and shoot it with a 45. See how far it moves...
