Good is a relative term, but i'd say good would be around 1.5 MOA which would equate to about 1.5" at 100yards. Maybe your gun just doesn't like that round? I've generally heard good things about RRA's accuracy. Maybe buy a could different boxes of all different types of bullet weights and manufacturers and see if you can get your group down some.
Let us know what you can get in down to!
