Just built a 6 Creedmoor, it shoots just as good, if not better than my 6BRs. While breaking in the barrel I shot a 30 round group @ 100 yards that the out side measurement of that group is 3/8". Its a boring gun as there no load development to do. I'm a big 6mm fan with having one 6 Creedmoor more to come, seven 6BR, nine 243AI, and seventeen 243, two 240Wby, three 6 Dasher and two 6PPC. I would go with a 8 twist in case you want to shoot 1O5gr bullets as it will still shoot 80gr up with excellent accuracy. I would go with the 6 Creedmoor but the 243 is also a excellent shooter that will shot tiny bugholes for you. The 243 is easier to find good brass as Creedmore brass is still kinda of new. The 243 been around for a long time, who knows how long the Creedmore will be around.
