I had 2 Anschutz 250s. They were ok to shot but not as nice as GISS or FWB300
But maybe the oil damper can be tinkered with. Maybe it should be only half full instead of full for best shooting behaviour. I dont know.
Its a weak system, with several weak points. As such, it was anschutz's 'worst' design.
Theyre easy to work on though fortunately.
