I would imagine they didn't want a round to telescope using automatic weapons.. As it appears, it shouldn't have any effect on loading or shooting... I will probably put a, "correct for my purpose!"cannalure on them just the same.. I'm mostly after the 93 gr. ball aspect of the bullet... Best to all, til...lat'r....GT

GT,

So the Swiss load that you saw is using the bullet cannalure for a place to indent/crimp the upper brass neck, not the case mouth, into? Most interesting to say the least. Some of the American ammo, especially the SD ammo, has a case cannalure to help keep the bullet from moving deeper into the case and raising the case pressure. Many of the SD rounds get chambered many times before they ever get shot.
