Bill: I think your assessment is right on. The targets are set too far for trad shooters, regardless of skill levels. I agree, too, with Rod. Counting all the rings, a course can be made quite challenging (or at least separate the top shooters)and still give the average shooters a good time. Around here at most any 3-D shoot, several compounders will clean the course, i.e., shoot a perfect score. A few more will come within a few rings/points of doing so. Even when the courses are set at what I would consider fairly close ranges for trad shooters, no one ever comes close to cleaning it. I've never seen it done in my more than 30 years of target shooting, even before 3-D targets were available.
It's been my experience that most but not all clubs, though primarily comprised of wheel shooters, want to accommodate traditional shooters. At almost every non-exclusive trad shoot I attend, I, and other trad shooters, are asked if we felt the course was set up right for us. And they incorporate that feedback into the way they set the course the next time. One or two clubs don't seem to care and continue to set the trad stakes very long. They get very few trad shooters. Perhaps that's the way they want it.
