Confusing load data - 7mm Rem Mag
I bought a box of Nosler 160gr Accubond Spitzer bullets and am looking for load data for H4831SC powder.
My Lyman book says this:
160gr Jacketed A-Frame bullet
58gr start (48,900psi) - 65gr max (58,500psi)
The Hodgdon website says:
160gr Nosler Partition bullet
58gr start (46,400psi) - 60gr max (49,800psi)
I'm confused. Why such differences in the start and max pressures?
Nosler's website shows load data the same for the Partition and Accubond 160gr bullets but only shows data for IMR powder.
Can anyone look up what they Speer manual says or put in their 2cents.

Here's a site I found for the actual 160gr accubond bullet:
http://www.reloadersnest.com/detail....60&LoadID=8160
It's showing 64gr and are saying it's right under the max.
This value jives with my Lyman manual.
