I've got a lot of Winchester Ranger T ammo in 9mm and 40. Got one box of Gold Dots in both calibers too. I've been under the impression that both types of ammo are kinda advanced in the art of putting holes in people.

Don't want to ever get shot by either, but If I had to make a choice...I'd pick the 9mm.

I've heard a lot of people say the 9mm has been improved, but if the same ammo is available in 40, I don't see how it could be better.
