a few weeks
Hi, the ranger is a couple of months old but have only put through approx 100 shots. Filled to 250bar and first 10 shots were lower through the chrono average 920. next 20 average approx 940 and last 10 average 915. Fill pressure at this stage was approx 180bar. was thinking of turning down slightly. When i was shooting at a target accuracy seemed to improve at lower end of fill pressure.
Your group is excellent at 100 yards.
