Does anyone know how long these bullets will be around or if sierra has plans to make them a standard bullet in the fleet? Also where the best place to get them? Putting parts together for a snipetac (.338 or .375) Would really like the .375 since i already have an edge in the works but am just worried about availability of the 350 SMK. Found one website that was selling 100ct. for $98 and seen them as high as $250 for 100ct.
