Not sure what's up with the data. My Speer manual says 5.6 max, my Lee manual says 5.1.

weird, my Lyman Manual (48th edition) shows 5.8 grains Max for a 225 grain cast for 902fps. and Hodgdon shows 5.3 grains Max.
the Data really seems to be all over the place.
my cases didn't show any high pressure signs so I imagine it's okay but it sure had a lot more kick compared to Winchester white box.
