This is the first time I've heard of a 625 that will not function with Federal brass. My three 625s function with everything and anything out there in any steel moonclip that I have ever tried. Frankly I am amazed that the .45 ACP moonclip platform is so flexible and reliable. Most other cartridges will be very picky when moonclipped and cases will need to be sorted, but not with the .45 ACP.

You can use very light or heavy loads, within reason. I would suggest that if you plan to shoot very heavy loads you not chamfer the chambers, or if you must, then do it very lightly.
