After a decade and a half of reloading I've read many a warning about reducing powder charges when changing to a magnum primer. I've always heeded it but time after time I've found an fps difference of about 25-50 fps in rifles and a similar difference in pistols. In many cases there was almost no difference at all, more so in pistol rounds. In 1 instance with the 357 magnum, mag primers were slower with 2 different powders throughout a range of charges.
So I decided to stop wasting powder and just go for it when loading under max. Call me crazy but I just can't justify down loading every time for no good reason. If anything I've learned that just about every old timer I know has a personal hunting load at or a half grain or better over max published charges. There's probably a bigger pressure situation from changing brass versus primers in most cases. Anyhow, comments welcomed.
