As Deadshot2 pointed out, the design has less tendency to erode in the throat, the 6.5-284 is known to be hard on barrels. From what I've read after a certain round count there has been projectile fragmentation(seems random across the board and not specific to a manufacture). It's theorized its due to the wider lands which are squeezing the bullet with more force while having a lower bearing surface ratio. Hence the higher velocities. Possibly the answer is to shoot bullets with thick jacket designs.

Thanks for the feedback guys.
