If you want to be competitive, you can count the 308 out. (LOVE that caliber but can't hang with the other two in competition, especially with a 20" tube) Big decider between .243 and 6.5 cm is if you handload. 6.5cm has arguably the best factory match loads avalable (Hornady, copper creek, ABM) and you will get longer barrel life than with the .243. Now if you handload the .243 can be just as competitive as the 6.5, but keep in mind you will want to start saving for a new barrel pushing the 105gr match bullets and up at competitive velocities. And if this is a hunting rifle as well, you will carry more energy further with the 6.5. Just my .2
