Those really shine with large calibers (400 to 500 grain bullet at about 2100 to 2200fps) with two triggers at stopping charges at five to 10 paces though unlike Mauser can be defeated by grain of sand into the action. Their owners claim typical mass-produced small caliber French Chapuis is good well past 150m perhaps even past 200m. Not sure if that is so because for same coin I would rather take custom engraved bolt gun or semi-autho instead.
