I thought the 9mm had MORE velocity and MORE penetration vs a 45ACP while the .45 ACP had less velocity but would cause a bigger hole in the target. This chart seems inaccurate. Isn't the 9mm vs 45acp the whole "small, fast moving bullet vs the slow, bigger bullet"??? That's what I've read everywhere.. 9mm is small, but fast moving and tends to over penetrate but cause less of a "big impact hole".

Then again it is just a chart. I could probably look up another chart as find opposite results. Every chart has their different "stats".....
