yeh, try to find out. chances are they used rws load which is not going to be on local shelves in that colt. one never knows because i had rifle from german company where 300gr a-square solids were used to adjust express sights!
i'm not believer of targets included with firearms. just look at cz were holes seem to be done with paper punch and no cartridge data is provided. i had two crude cz 602s in the past and they were both excellent shooters.
