Just an FYI, this is what the NRA rulebook says about it:
"19.9 Obsolete Classifications and Scores—All classifications and scores (including temporary, Rule 19.14) except Master, shall become obsolete if the competitor does not fire in NRA competition within the discipline in which the classification was earned, at least once during three successive calender years. Master classifications and scores shall become obsolete if the competitor does not fire in NRA competition of the appropriate discipline at least once during five consecutive calender years. Lifetime Master Classifications will not become obsolete. "
This never made sense to me. First, because if your Master classification expires, you are now... a Master (unclassified). Also, a high master doesn't become a sharpshooter after taking a few years off. Seems unnecessary. If people take a long break and it turns out they now suck, there are already provisions for reclassifying downward.
I'm not arguing for or against, just pointing out what the rule states.
