It depends on what you are looking for in a secondary upper. The 6.5 is a great round for longer shots. It shoots flatter than the 6.8, but the bullet choices are slimmer. The 6.8 is a great "thumper" round. It's a 300yd round.......period. It drops off quite fast depending upon bullet weight. I shoot the 6.8 SPC at night for a reason. It drops animals in their tracks. It's surely not a 500yd gun. I set mine to 0 at 200yds and at 300 it's 3 to 4 inches low. I don't even know what it does at 400 and 500, nor do I care. I shoot 110 vmax, 90 speer TnT, or 85 TSX. I like the lower weights in 6.8 for flatter shooting. The mass produced 115gr stuff shoots good, but looses trajectory even faster. Also, if reloading, go with the SSA or Barret brass and the small rifle primer. The Remington brass with large rifle primers are not nearly as consistent out of my 700.
