Berry's 9mm 124 hp
Woohoo! First reloading question! I'm trying to load Berry's 124gr hp plated 9mm bullets with Winchester 231. I haven't even got to the charge yet, but I'm having trouble with OAL. At the length I've used for lead (1.15in), These really don't want to fit in the chamber. Even at 1.10in its a bit of a squeeze. I've not loaded any hp before.
As far as the charge goes, I've heard people saying that plated bullets are loaded to lead specs and also that they are loaded to the low end of jacketed levels. I load lead 125gr at 3.5gr and jacketed 124gr at 4.3gr, so that's a pretty big difference.
