  Picture of the bullet, I bet we can figure out what it is. There are very few 77 grain bullets on the market.

  These came from a benchrest shooter.
  He gave me all different weight grains in a bag and I sorted them by weight.
  Apparently there are two different brands here.

  Those would be siera's, both of them.
