Anyone Use Quickload or similar?

Has anyone used Quickload or one of the other internal ballistics software packages for pistol loads? Does it agree with actual results? Everything I've seen refers to it's use in rifle loads. I'm just curious if it will work as well for pistol.

and... before anyone says it, yes, I know that using any of the several "standard" bullseye loads and testing them in the real world will be a better solution. I have accurate bullseye loads. I'm just curious.

I had a guy use it for me trying to get Bullseye pistol loads for International Clays in 38 Special. I haven’t shot enough of these loads to get a feel of how it works.
