Currywurst

I would take a look at the chamber. Maybe it needs some polishing.

The German magazine Caliber tested the S2 Orange in Feb. 2020. 10 shot groups at 25 meters from a Ransom rest. Groups averaged 55 mm (2.2''). Geco bulk ammo was 51 mm, just over 2''. Can't recall Shadow 2 results but the same Geco stuff gave them 60 mm (2.4'') with a Shadow 1 a few years back. The Orange does not seem that much of an improvement in mechanical accuracy.
