Loads tested in Tikka Tactical 24" barrel, some signs of over pressure (flattened primers, some stamping of bolt face on brass - bolt release was easy however) as rated load should only deliver 2650 fps, I was at 43.53 to 43.55 grains thrown in LC cases.

Accuracy was good, shooter not so good, mirage was funky. Distance was at 200 yards at Burro far right side which is only 2 feet over the rocks and grass, hence the mirage.
