Mine likes Hornady' s 140 grain light magnum (1/2" groups at 100 yards) but I hope that there new one with the 130 grain SST will be as accurate. They have the SST for handloads, but last time I checked they were not in factory ammo yet. They are supposed to have them out before this fall though.

The SST should hold together better than the interlock in the 140' s which are basically the same thing as a core lock. Pretty good unless you hit a big bone.
