So the first thing you should look at when choosing ammo is seeing which bullet is appropriate for your twist rate. The B14 7 mag is a 1:9.5 twist which means it is going to stabilize and shoot the best with the 165-grain area. If you go up to the 180s you are not going to stabilize the bullets, and the 150-grain class will be overtwisting.
So now that we know what bullet range will work the best, see what factory options are offered for that range.

Those are the 5 options that I would stick with and go see what you can find. The accubonds will probably hold together a little better if you like high shoulder shots but the ELDX is going to do everything that you need. Depending on how far you are shooting will change how much you test the ammo but those are the starting points.
