Scott, I find it devious that you describe my choice to buy a 4-16x scope as self-serving, while at the same time state you may be pressed to acquire new equipment to shoot Hunter at 16x.
Not only devious, but also disingenuous, because I know you can simply pick up your existing Diana 54 with its UTG 6-24x50 you used to WIN Open Piston at Ennice to shoot Hunter piston going forward... without skipping a step. I believe it has a 16x marking.
My bet is you already have several
Leapers/UTG/CenterPoint scopes with 16x markings. I have several myself. I can send you one if you're strapped (but I know you aren't, LOL).
I bought my current scope two years ago, fully anticipating what I believe to be the inevitable switch to 16x. Time will tell if I anticipated correctly.
