Pull down ball 9mm NATO powder. I have 5lbs I picked up at knob creek probably about 5 years ago. I can't find any data to load with. I've got everything from 115 Fmjs to 147 lead. Any help or links would be great. Personal experience is also much appreciated.
WPR 289 is the non-cannister OEM equivalent of Winchester WAP and was used for a while in the M882 9mm round. Winchester WAP has been discontinued as a commercial product so there isn't any data available on the Hodgdon website. I have data for WAP in my Speer #12 manual if you need it, but I imagine you have a few older manuals around with WAP data in them. Since your powder is non-cannister pull-down, the lot-to-lot variability is higher than commercial stuff so you will want to start with the WAP start load and work up. The Speer manual gives data for WAP with 100gr jacketed, 115gr jacketed, 124gr jacketed, 147gr jacketed, and 125gr lead RN.
