Hi Guys I am new to the forum.
I hope someone can explain whats happening with my S510 PCP.
Essentially, if I leave the gun rest for a few days the zero is always off on resumption. Its always shooting about 2 inches low. But the confusing part of it is after 3-5 shots its nearly back at its original zero. Before I understood what was happening I was re-zeroing and then needed to re-zero again
I use JSB Pellets which are very accurate once I get beyond the initial shots.
Anyone experience this issue?
