The 6 CM was extremely popular in practical-style rifle matches, but the 6BR and its variants are dominant in that arena now. The 6 CM burns too much powder, which leads to difficulty spotting shots because of recoil, and also shorter barrel life. I still shoot the 6 CM for these types of matches, but the trend is toward the BR family.
This is of course correct. The precision rifle game has always been fairly recoil adverse, and has become exceptionally so over time. Which is fine, but has lessened the already somewhat strained resemblance to hunting. The 6.5mmCM is clearly the most useful of the cartridges that came out of precision rifle from a hunting perspective. The 6mmCM is clearly next.
