52 grains of IMR4064 and a 150.
Old load still works good !
IMR 4064 is a universal powder for many cartridges as well as bullet weights, for those many rounds. IMR 4350, 7828 is temperature insensitive and is the only one in its line save the new power recently 4166. Over the years l found suitable powders for a few cartridges l load for. For awhile it was guess work, until l started to get tired of wasting time and money on components and trips to the range with loads that weren’t consistent. Along with a good recipe comes good loading techniques as well as a good platform to shoot from and shooting skills.
