So you have to join a club to shoot in Marryland? That's the bee's knees. From reading those definitions above, I can see where you're coming from. I know what you mean now. Like the guys at outdoor ranges that aim for the wooden target supports, or have more money invested in Tapco junk than they do their rifle?
Sorry for sounding like a wise-ass, but us Texas folk have different definitions of plinking. It would seem to me that a range that prohibits 7/15 yd shooting would be very strict on rapid fire and non-target shooting.
It is imperative to strike down the rise of modernism which would lend itself to folly such as the use of billet components.
