I would stay with the 76 gr and move the bullet out to about .020" off the lands. I have seen them shoot pretty good from .005" in the lands to .020" off. Also if you coud get ahold of some Fed 215 GM primers or even some 210's I would try a primer change too.
Another thought is you could have some barrel pressure and was getting heat by the time you got to those loads. Maybe load some more and retest making sure the barrel is cool for the 3rd shot.
