would a 6br be a logical choice?
Nope.
For 100/200 yard group shooting you want a 6ppc. Least recoil and smallest explosion in a very efficient case.
If I were going to take the bigger explosion of the BR case I would use the more efficient 30 caliber version and use for group and score. The case capacity for a 6mm bullet is a little over kill for 100/200 yards but perfect for 600. The 30 caliber barrel will last twice as long as the 6mm version.
