[QUOTE="Bart B, post: 738205, member: 5302"] Note that as the barrel wears out, the lands will start further away from the bolt face. Such is life as steel erodes away from hot gasses. .308's erode their lands about 1/10th inch over 4000 or so rounds; depends somewhat on the peak pressure of a given load and the powder type used.
