Our club (Palo Alto R&P Club, Louisiana) has always operated matches by the interpretation of the HP rules that all spotters must be the same size for all targets although the chosen size has some options. Many F-class shooters, including myself, prefer the 1.5" spotters at 600yds but being that we also host 'sling' classes at the same shoots we have stuck with the 3" spotter for all. I was surprised that shooters were able to choose spotter size for any particular match, sometimes even changing within a match, at the F-Class Nats in Raton. If there are any HP comp board members reading this I would appreciate your feedback as to the legality, in the eyes of the NRA, of 'mixing' spotters for different shooters. I certainly enjoyed the option of using a small spotter.
