  • For some reason the SC2 would not shoot this round at all. I thought it was the bullet, but it shot the corbon 139 just fine.
  • Uses Remington brass
  • Very good standard deviation and extreme spread
  • Fairly hot load, should provide excellent long range ballistics
  • A large lot of ammo was custom loaded for GA Precision, but continued availability is questionable.
