Hiya guys.....I was wondering if anyone could tell me what dials that came with this scope worked with which cartridges? I am hoping someone has this scope or one very similar. Its a bushnell banner, wide angle 3x - 9x 38mm scope with range finder and bullet drop compensator turret. It came with 3 knobs (all that I got it with that is). I have knobs 3a 3b and 3c. Thanks for any help. I will include a photo if needed later.
