perfect?

I shoot a 30-06 browning boss a-bolt 20" barrel, 165g sst Hornady superformance factory ammo

I screwed off the BOSS and put on a titianium deadair suppressor

adjusted it like the BOSS and get easy 3/4' groups

2900fps, 0.447 BC

virtually no noticeable kick

what could be wrong with this set up?
