After getting a zero at 100 yards with Sierra's 30 caliber match bullets, noting the atmospheric conditions and chronographing the load, using Sierra's ballistic software for long range zeros and using local conditions, my first shot at 300, 600, 800 and 1000 yards with three bullet weights and muzzle velocities were within 1/3 MOA of dead on. This is with aperture sights that had to be calibrated for the MOA value each click would make with the non-standard sight radius used on the rifles. Mailed Sierra Bullets an attaboy letter for their excellent software and published BC's for their bullets.
