Reloading data for 45 gap in 625

[sheriffoconee]

while ya'll debate whether or not GAP should exist (it is an excellent round in my Glock 38 and 39....but that is the subject of another post) I shoot GAP on and off out of my 22-4. Without a doubt, the Speer 200 grn TMJ and Gold Dots are the most accurate factory 45 rd, ACP or GAP I have fired out of that revolver.
Why is that??? I have no idea.
