If your gun shoots the LEs good, they are WELL worth the difference. I would test them at 200 yards or more though, as they cross the mach 2 line between 100 and 200 yards, which can introduce some instability into the trajectory.
The LEs shoot 1 hole groups in my 336C at 100 yards, but that opens up to about 3" at 200 yards, where as both Fed and Win 170s shoot 1" groups at 100 yards, but open to only 2" at 200 yards.
Anyway, that's been my experience with them, but as you know, all rifles and riflemen are different. JMO.
