230 grains is why I love the .45 to begin with. All the smaller cartridges rely on velocity and pushing the limits to do what the .45 does without breaking a sweat.
Even when you push it up a notch with .45 +P, it's still not breaking a sweat and it's performance has no equal with anything but the most powerful handgun cartridges.
Needless to say, I'm very happy with the .45 and the 230 grain bullet.
Take your Enzyte and carry that 10mm like the brute man you are.
