Load data for 7mm Rem Mag 175 grain Accubond Long Range?

[bubbat42]

Im trying to load some bear hunting rounds for my Remington 700 but there is no load data in the book or online for the AccuBond LR bullets. Im using RL22 powder and have tried the maximum of 62.5 grains as listed under the 175gr partitions but it seems like it is nowhere near the maximum. If I don't get any help on here berfore this weekend im going to work it up until I see the primers start to flatten out or the bolt starts to stick when ejecting the shell. Thats the only way I know how to tell if im at the max.

Any suggestions would be great
