I like my 6 creed. I have a 1-7 twist barrel. I shoot the 115 Berger at 3150 FPS for deer and I have loads for the 80, 95, and 103 eldx, and 105 hybrid. The 115s hit really hard, it's a fun rifle.
I assume your creed stabilizes the 115,s with an 8 twist? I am at only 800ft here in N Dakota and winters are cold dense air so I ordered a 7.83 twist bruxBiggest issue between the two if going factory is 10 twist vs 8 in the creed. I shoot both and the .243 is limited to 100 gr lower BC Bullets . I like the 6 creed for deer with a 115 Berger better than the 7"s. I run them over 3100 in 3 different barrels with rl 26. Drops deer dead at 800 yards . Have got exits on lung shots on elk with the 115 with lots of damage internally. 243 with 8 twist do the same thing. Utilize that powder capacity with the heavy bullets and they make a good 1000 gun. Shoot to a mile sometimes for fun !!
With the velocity I run and at 4700 ft elevation it is over 1.5 on Berger stability chart. Bc goes down 2% when below 20 degrees. I shoot them a lot at 1000 and 1200 yards and they shoot good. I might try a little faster twist on next barrel for the 115's or 110's but wouldn't go faster than 8 for the 105.I assume your creed stabilizes the 115,s with an 8 twist?

I hear you. Too fast a twist and it turns into a temperamental picky beastWith the velocity I run and at 4700 ft elevation it is over 1.5 on Berger stability chart.

Well, so far, I have refused to drink the Creedmoor Koolaide but between those two cartridges, I might would consider a 8t, 6mmCM. Nothing wrong with the .243Win and I've owned a throuple but it seems that the cases are always in need of trimming (20 degree shoulder). Make it an 8t, Ackley Improved and it would be a done deal for me. Good luck with your decision.I'm on the fence here, about to pull the trigger (pun intended) on a .243 but making sure I'm not going to wish I had looked into 6mm CM! Pros / Cons between the two mentioned would be appreciated..
