Well, since the rubber on the mags was standard, would have to consider their shelves higher.
I know what you mean about the hand being even with, even encroaching onto the shelf. Of course, Fred liked it that way, and it's become a marketing point lately. Until I measured them, I had no idea the Bear wood risers were cut that close to center/ the pivot point of the bow. On the other hand I did have a B Supreme riser a while back that broke the mold. The shelf was close to 1 1/2 inches above the center of the bow/pivot point of the grip. Bet you would have liked that one. Unfortunately, it was higher than I liked, and I sold it.
I'm sure Bear uses jigs/templates to make the major cuts on wood risers, but from what I've been able to gleen from the risers I've owned as well as info provided by others, there's a lot of variability, minor though it may be, which appears to be the result of the final finishing by individual Bear craftsman. There may be others like your 2017 out there, but almost have to have them in hand to decipher the difference.
