Were Werndl rifles converted to the later larger length cartridge always somehow "indicated" as such by (added) dates on the barrel or receiver? Were the sights always changed to reflect the new intended trajectories? Where were the conversions done (in whichever countries ? which is the most accurate long range cartridge for these? I have heard much conflicting information on how to identify the caliber properly when not actually in possession of the weapon(s) in question. I have also heard that all of the Werndl rifles were converted to the later loner cartridge( which I personally don't believe because they all went (or didn't go!) to various countries ! Thanks!!
