More than likely you can find a better shooting bullet....and probably for a bit less than $55 a box.
If you can't I would suggest selling the rifle and getting another. While 2" at 100 yards will kill game all day I see no reason to spend your hard earned money on a rifle that should be shooting better than that.
Like I said before though, you should be able to find ammo that shoots better than the groups you are getting now.
Unless the gun has an accuracy guarantee, every gunmaker will tell you that there is nothing wrong with a 2" group.
