I have nothing against the chassis rifle.
It looks like an interesting study on doing a rigid and condition-resistant stock in classic style.
It's a Purdey after all, and each rifle can be styled and appointed as the rifleman chooses.

The name of the game with the chassis system rifles is consistent first round hits at distance. Not exactly the same job as fast snap shots over express sights.
More power to them.

Cheers
