A 21" 7-08 with 180's does thusly,in this morning's atmosphere. Hint.
It loses less than 1000fps of velocity,at the 1000yd line and makes 1000ft lbs of "energy" at 1000yds,if only for conversation. Simply looking through the scope,will get it past 1100yds and one can juggle 30 MPH full value winds at 1100yds easily. Hint.
Just sayin'.................
