While such performances from the .243 case do happen, the frequency thereof is typically short lived. David Tubb was probably the first to use the .243 Win. round in high power match rifle competition and did very well with it. But as both he and Barrett (Boots) Obermeyer (barrel maker extraordinaire) told me, it starts loosing accuracy very quickly at about 1500 rounds. Its overbore capactiy powder charges coupled with max (and sometimes +P loads) eats away the leade in a hurry. But it's got twice the super accurate barrel life of its half millimeter larger bigger-case cousin, the 6.5x.284 having about 750 rounds before going south.
