No problem. And just FYI, I found zero "published" data for CFEP in 124 gr of any variety. If you have any question just holler, we are here to help. That's the beauty of THR, a group of folks who do what we can to help when we can.
If you run Android I suggest looking for "reloading assistant" app. It's free on Android and hits all the big powder company sites and shows their data. On IOS that same app costs a couple bucks, but the powder companies list their data for free. If you ever run into a situation like this where you can't find data, you can often email them telling them what bullet and powder you are using and they will probably have data that they didn't publish, usually because it didn't perform well or maybe they just didn't think it would be popular enough to take up bandwidth.
And always load short for autoloaders...you want the neck tension on the bullet when the slide rams it home. It's unsafe on both ends if the bullet slips. If it jams a bit but still manages to chamber, the bullet can be pushed deeper into the case ramping pressure up to a dangerous level. If the bullet slides forward when the case gets stopped suddenly as it headspaces then it can get into the rifling and cause pressure spikes before the bullet manages to move against the lands. Normally the few thousandths a bullet jumps before getting into the lands gives it enough momentum to go on through without major pressure spikes.
