[QUOTE="jmden, post: 790410, member: 1742"] Go with the 215 Berger and H1000 or Retumbo. Did you have changing lighting conditions during the string? Typically the best conditions for accuracy and consistency of the chrono are consistently overcast (cloudy) conditions. Sunny conditions can result in higher readings. Changing lighting conditions can cause different reading coming from the chrono. Using a micrometer seating die and a Davidson's seating depth checker to get the most consistent seating depths is something else to consider as well. Is your bullet seating die seating plug for VLD style bullets? The alternative style has a much larger opening often causing VLD style bullets to make contact with the plug at their tip and not far down on the ogive, which is much preferable for consistent seating depths. Is your chrono stable and not moving in the wind? Are you sure you are shooting through it at the same exact angle, etc. for every shot (shooting off a bench, or prone off bipod to increase consistency in this regard)? I put my chrono 10 yds out to keep any chance of muzzle blast from moving the chrono and causing a bad reading as the bullet is passing through. [/QUOTE]
