Strange thing is that the Hodgdon 8th Manual (p527) says that the H414.58.5gr load under a 165gr bullet (post #2 above) is likely "OK" -- though max.
The Hodgdon website, however, says:
165 GR. SIE SPBT
Min: 51.0gr 2,678fps 41,900 CUP
Max: 56.5gr 2,877fps 49,700 CUP
It's also in CUP... which make me think it's old data.
(Note I didn't say bad data, just likely to be "dated data"
This is why reloaders have to be thinking all the time.
