Running the numbers with velocities capable from the 7 rem mag, the 162 ELD M keeps up with it to 1000 yards. The 180 has a little less drift and more energy. But the 162 is stabile in "standard twist". I think the 180 has to be ran in something a little faster than a 7 Rem mag to really make a huge difference out to 1000 yards... It has been shown that when the SG factor gets at 2 or above the BC increases slightly... So I guess what ever you shoot the 180 in, the 162 could benefit as well.... So personally I believe the 162-168 class bullets seem to be optimum to 1000 yards...
