I use a LCT for my lower-volume reloading (which includes all rifle loading that I do) and save my 650 for USPSA and other high-volume loading. Changing calibers on the 650 is always a bit of a chore for me. I suppose if I did it all the time, I'd get very proficient at it. But it's such a chore that I don't want to do it much, so I don't do it much, so I'm not fast at it.
