Thank you Butlersrangers, you raise an interesting point. I was wondering about drift compensation, but the rifling is left-hand twist in this Berthier. I remember that when zeroing my L.39 on the 25m zero range for long range shooting at Bisley years ago, I was taught to zero the wind 1 minute left of the aiming mark for that rifle's right hand twist. The idea was that the clockwise-spinning bullet would fly back in to the right over longer distances. I'm certainly no "aerodramaticist", but I would therefore expect an anti-clockwise spinning bullet to veer left over long distances. If the berthier was printing a minute right then it would seem likely that the designers had compensation in mind, but I am skeptical. However, I never tire of being proven wrong, so I will certainly see how she performs at 100 and 200 yds and report back.
Cheers
