I was really just thinking out loud on the pressure issue. I really don't know, one way or the other. For performance loads in 45 acp with 200gr bullets I use AA7, which gives me right at 1100fps from a 5" revolver at published max. Beats published performance, but I do that from time to time with AA's data. Over pressure? Beats me. Not enough to hurt a 625, for sure.
