I just started reloading a few months ago so forgive my ignorance if thats all this is, but this really seems to be a conflict here.
I was looking at Hogdons website, at their reloading data and this really struck me as having something seriously wrong.
Both are 125 GR. CAST LRNFP using Universal powder.
versus
I realize that some powders are funny that way, but the 38 special data uses (4.3gr / 872fps / 8,700 CUP) as its starting load, so apparently 4.7 shouldnt be that far off the chart.
Are these charts just wrong or is this really that complex ?

357 magnum
125 GR. CAST LRNFP Hodgdon Universal / .358" / 1.580" / 4.8gr 1046fps / 11,000 CUP ---- 6.8gr / 1401fps / 34,200 CUP
versus
Now, how can, using the same bullet, the 4.8 gr of unversal be 11000 cup on the 357 chart....but on the 38 special chart 4.7gr, .1 gr less, be 16,800 CUP ????38 Special
125 GR. CAST LRNFP Hodgdon Universal / .358" / 1.445" / 4.3gr / 872fps / 8,700 CUP----4.7gr / 1036fps / 16,800 CUP
