Barometric Pressure: 29.68 inches of Hg
Humidity: 62%

10-shot groups fired from one of my precision AR-15s with a Lothar-Walther barrel with a 223 Wylde chamber and a 1:8” twist. The groups were fired from the bench at a distance of 100 yards with the same sight settings on the scope for each of the three groups.
