Leupold LR/T vs. ER/T

[bbartsch]

Can anyone tell me the difference between these two pieces of glass? The ER/T advertises as being for 2,000 yd shooting but I can't see how. It has 70 moa of adjustment and the LR/T has 75. The tube size is the same, so I am struggling with this a bit. I wrote to Leupold but never received a reply. Hoping one of you gurus might know.

Just received answer back from Leupold. " The ERT stands for front focal plane which you can use any power for milling vs LR/T is 2nd focal plane which you must keep it on high power for milling only. "

" The ERT stands for front focal plane [...]. "

Lol, wonder what FFP stands for, then...
