Rule 170.50 defines Master as: "The competitor is classified "master" or above in NRA, PPC, IDPA, IPSC/USPSA, Cowboy Action or similar shooting disciplines." After 3 years, I became classified as Master in High Power Rifle. My understanding of the rule would be that I am no longer an Amateur for GSSF competition because of my NRA classification. However, I can see where some would say that this classification is not a "similar shooting discipline." Based on my handgun shooting ability (and scores in GSSF competition) I can guarantee that being good in high power rifle competition is of absolutely no help with Glocks in GSSF competition. The question: In light of the rule, do I enter GSSF matches as a Master or Amateur?
