Switched back to original pellet and shot two 5 shot groups.
Unregulated S510 starting at 1.9 bar and ending up at about 1.25 bar with no scope adjustments except for the one after the first shot. Only 35 yards.
Still getting some fliers which most likely reflects on the shooter and not the rifle. Not pellet on pellet for sure but I’m getting a few more in the bull.
Was glad to see two different pellets shot close to the same point.
