Tuning plunger for Nanos

Today I was just tuning the other plunger to Nanos, inside. I changed the plunger and started shooting distancies 5 - 25m. Arrows was little to the left, so I made the walking test, and tuned the plunger. After couple time of tuning and testing, distancies 5, 10, 15, 20 and 25m was in the middle. Maybe on wednesday I go outside to take my new distance marks. 5m and 10m was not changed, but longer than that has been changed. Good feeling after this test day...
