I have 4 using IMR powders from Loaddata.com. They are however with a 165 gr. cast, and are max loads. I do think they can be used to get you started, ( reduce a little to start). They are: IMR 4198 30.0 grs. 2,250fps., IMR 4895 32.0 grs. 2,200 fps., IMR 3031 33.5 grs. 2,250 fps., IMR 4320 36.5 grs. 2,200 fps. All bullets were sized at .322" . I hope this helps.
