[QUOTE="Browninglover1, post: 772633, member: 29966"] The 1st focal plane scopes allow the reticle subtensions to be accurate at all powers. For example: my Sightron 6-24 with a mil dot reticle is calibrated to accurately measure 1 mil at 24x. If the scope was a 1st focal plane the reticle changes size with power changes so that the mil dots are always 1 mil apart. This basically allows you to use the reticle for holdovers, range estimations or shooting corrections at any power instead of a specified power like on a 2nd focal plane scope. [/QUOTE]
