I'm with jcunclejoe. My match rifle(Finnish Lion) did far better with RWS Match or R50, Eley 10X, Match, or even good lots of Club, or Lapua than it did with CCI. Further, I don't believe for a moment that any reasonably skilled shooter would get different results.
CCI have a different bullet shape than the others and some of my rifles have a marked dislike for it.
As a matter of interest, why not have a look at what's being used by your aspiring national rifle team members.
