K9, you will get 3x the barrel life out of a 6 BR over a 6 Creed! NOT to mention, the amazing accuracy with a flock of powders and bullets with the 6 BR.
The 6 Creed is on par with a 6/250 AI, and they are not easy on barrels, I shot out two of them with AA2700 being your friend when it comes to the heat index on how hot they burn.
