Nosler test's their loads out I think, so I would go with the Nosler published data.

Huntr Pat,
Data from different sources will not necessarily prove identical. This is because differing components may have been used (brass, primers), differing length of barrels and differing set-ups likely have been used, and also because of differences in powder burn rates. For this reason, you are always well advised to work up from the minimum charge recommended to verify that the load maximum listed is safe in your rifle. Ultimately, you are responsible for the safety of the load.

If you're loading the AccuBond, following Nosler's load data is a good place to start, especially if you're relatively new to handloading. As DrMike has said, different testing (components, barrels, labs) will yield different results, but starting at the start charge and working up carefully will almost always get you where you need to go.
