    @Danny I have a CZ FS that has a 20.5" barrel so probably can't offer any help/direction. Mine does however shoot 162 Eld-x's sub MOA running 2209 with iron sights (not over crono). Feels better on the shoulder than my Mannlicher FS 270. @Tentman sorry for being so slack, free over the next 3 day's!
