While I'm a supporter of the 6.5 PRC and think it will prove to be a good round, note that the magazines don't say anything about it being a barrel burner, yet the 264 WM continues to be labeled. Both 264 & 6.5 PRC ballistics are nearly identical. I have a Sendero 264 and love it, but do wish it had a 1:8 twist for the heavier bullets. Mine will shoot 130's but not as accurately as 120's. 140 boat tails are not an option for under 1 MOA. Enjoy the PRC!
