And today the spring broke!
After a few thousands pellets the velocity dropped from 850fsp to 769fps with JSB 8.44 with a ES of 10-15 fpsThe only lube I'm is the Krytox GPL 205 GreaseBelow target was shot at 23Y indoor a few days ago (at that time the velocity was 811 FSP with JSB 8.44).If the energy drops below 11FPE, I'll probably have to change the power setting from low to medium.
