I think accuracy issues have become quite common with them, possibly due to variances in pellet manufacturing? My friend's 100 has been pretty spot on in the time he's had it but in more recent years the barrel has fouled up a bit causing loss of accuracy. My own one has been quite bad for fouling but with lubricated pellets it seems to wash the deposits out and keep it more consistent.

I wonder if Weihrauch's QC has taken a dive with their newer stock. I certainly can't say I've heard of anyone complaining about loose actions in the stocks. It could explain a few things for sure.
