Shot the new Criterion 308 bull barrel yesterday in gale force winds. the 155 gr A-Max is showing promise at .608" at 100 yards using RL-15. In 168 gr SMK loads, I tried Win 760, all loads tested were within 3/4" and slightly under giving velocities in the 2720 to 2730 fps range. Best load was 45.2 grains yielding SD/ES of 7/17, velocity of 2720 fps and five shot group of .740". With the heavy bull barrel, the rifle seems to ride the bags well in a Duramaxx stock. So far, I have not glass bedded the action. Total rounds down the barrel is at 40.
