Hello .303 British reloaders... I'd like to reload some Hornady 150 gr Spire Pt .312" bullets , and have found some big discrepancies in the load data...
From the Hodgdon on-line website I find this H335 data:
150 GR. HDY SP Hodgdon H335 .312" 2.995"
37.0 2430 34,700 CUP
42.0 2706 43,100 CUP
From my Hodgdon #26 loading manual , this is what it says for the 150 gr bullet:
44 grs 2574 fps Start
48 grs 2729 fps Max
What gives?..Is Hodgdon just playing it safe nowadays?....Anyone care to speculate on this big difference in powder charges?
Thanks
Bob
