One group "sub-MOA" + one group "3 MOA" + one group "2 MOA". 1 + 3+2= You have 6 divided by 3 equals 2 MOA.
Your best hope is to shoot some of the previously accurate ammo to get a muzzle velocity range and then try to replicate the load with your handloading. You may find that the previous load is now a 2MOA shooter vs what you had before. If so, you may have something going on mechanically with the rifle/optic/operator.
