What is the difference of in field, finger. and target knobs? I am guessing they are all 1/4 value. So I guess my question is does one have more travel that others. I know the height of the target knobs as that is what i have on my 6.5-20lr. Are the other two just normal hunting adjustments? Some insight please as i am by no means the sharpest tool in the shed.
thanks in advance
