The 6-284 data is decades old, note there are no powders newer than those used 25+ years ago. I remember questioning this data in the mid-1990s, the max velocity was well behind the 6.5-‘06 and the 6.5 mm Magnum in spite of having almost the same case capacity. But being a wildcat there was no standard chamber so throating etc is unknown. You can find similar odd data in many manuals if you look at enough of them. The OP has hardly discovered something new.
