I have shot my friends 450/400 couple of times.

Rifle feels slim but compact and shoots straight.

Due to thick barrel walls feels nose heavy i.e. swings slow, but one can get used to. Triggers are crisp.

Sights are decent

Cocking feature is alright, you cock it on the way to the shoulder amd once you get used to it became second nature - much better than on Blaser S2, since the rifle stays cocked when reloading while S2 has to be cocked every time you open/close it.
