Area 419 Billet Anodized Loading block has 50 places of 308 Magnum or Lapua bolt faced rounds (Cheytac blocks have 36 places). Features rubber pads on the bottom to keep from sliding around. Block is machined in house from 6061-T6 Aluminum. Dimensions are 9.5″ x 4″ x 5/8″. Holes are 0.500″ deep and are a tight fit around the case to prevent tipping over. Hole bottoms have a small “divot” in the very center to catch powder kernels and prevent any possible accidents with primers.
