I have on in 6mm Creedmoor. No fuss in torqueing it on, was .0005" tighter in HS than my last barrel from ALTUS (probably variance in thread stretch or torque value). Using the same load, after 150-ish rounds it was within 10 FPS avg of my last Proof prefit from ALTUS with the same load, seating depth, etc...
As long as they have them, that's my go to Impact barrel, cant beat the price.
