This may have been asked previously in the past - if so sorry, I don't visit this forum very often but I am curious. Is the 6.5 X 55 legal for F class precision rifle and if it is, are shooters using it? It would seem to be a natural with its low recoil, lower muzzle blast and inherent accuracy (according to the Swedes). How does it perform at the longer ranges past 800 meters? The BC for the bullets are very high so it should be excellent at the longer ranges. Would this caliber be a good base on which to build a precision rifle for competition?
