  • 4″ longer barrel gains 134 fps over the SC2!
  • Excellent velocity combined with excellent accuracy makes an excellent long range load
  • While still not close to the claimed 3000 fps, it is still excellent velocity.
  • At 2900 fps the long range ballistics will match the 300 Win Mag 190gr Match
