I have a good supply of Winchester Action Powder 289 at a good price (in New Zealand) but can find no loading data . In particular I want to use it in 38 special and 44 Magnum pistols. The 38 will be with 148grain wadcutters and 158 grain swc. The 44magnum with 180grain wadcutters and 240 grain swc. All boolits blended lead alloys. I would well pleased if any knowledgeable and helpful person would share whatever information they can with me.
