Not from what I've seen but maybe your tests results were somehow different than mine.

There isn't enough street data on the 10mm nor any commercially available loads in 10mm that are scientifically/professionally tested to the same standards as most Law Enforcement grade ammunition.

As a result, there isn't much real world data available on the subject. Yes, there is some but much of it is either inconclusive or incomplete.

I don't like betting on maybe or it probably won't. Granted, my tests with several 10mm loads were in no way scientific but the results with the 10mm loads almost all over penetrated when compared to other popular calibers such as .40 S&W, .45 ACP, and .357 Mag.

None of the loads tested in any of the other calibers showed any over penetration where the 10mm did nearly every time. We obtained average to really impressive expansion on the loads tested but we had severe over penetration issues with most of them.

To sum it up, the 10mm has a lot of power behind it and it shows in the form of over penetration. With hand loads that were toned down a good bit (closer to .40 S&W velocities) over penetration wasn't a issue and expansion wasn't as impressive with some bullets either.

I'm not here to tell anyone that carries this cartridge that they should reconsider it. All I'm stating is what my experience has been with the cartridge and why I feel the way I do about it.

In short, it's not for me.
