Can someone that REALLY knows about ammo tell me why on all ballistics charts the 40s&w out performs the 45acp????? Unless it's +P 45 ammo....

Because its faster and smaller and weighs less and you can't see it come out the barrel......the same reason a 9mm will go through more water jugs and phone books than both of them.

Right but in talking energy FT-lbs. at 50 here are the 45 and 40 FT charts
Thanx for any thought on this????

keep in mind the difference between caliber and cartidge combos. The difference between a .45 and a .40 is .05. The cartridge is what we are really talking about. someone will have to correct me here but I believe the .40S&W has a higher chamber pressure. combine that with faster velocity and you have a bullet that can put as much if not more energy on impact. That however does not tell you what it will do in a body. IMHO no one can tell you that. There are thousands of veriables.

IMHO energy on impact is the only reliable way (that I currently know of) to compare two different cartridges.

See it come out the barrel?

I'm guessing he's trying to emphasize the slower velocity which makes it easier to see the bullet in flight.

I have seen my own 9mm bullets in flight (when the light catches it the right way you can see the flash of the jacket); it's not impossible.

You can see a .45acp leaving the barrel, its just at threshold where its faster than the eye....around 900fps and slower...

Ok I work with a bunch of PhDs and we get in some strange conversations. We had this discussion and could not figure out how someone can see a fast bullet such as a .22. One of the guys found a high speed photo of a bullet that was putting off a contrail. Since the normal humidity is very low around here it took a while but one day when it was lightly raining we had a “field trip” and sure enough at the correct angle and against the right background you could see a “shadow” go down range. It seemed .22 hyper-velocity from a rifle was easier to see then any of the hand gun rounds. However I am getting to close to old and could not see any of them. But the younger guys swore they could see them.

The last time I saw a "bullet" in flight was off the coast of Vietnam. a 16" bullet.
