I haven't noticed much difference between the 140eldm and 108eldm. In two bull elk and a few antelope.
Mine is also 16” and I got x-terminator to push the vmax to 2750 so not much difference. I just tested the 95gr TMK today and got 2664 with h335. Just need to find some more in stock. It passes my vmax load at about 250 yards and velocity is 1800+ out to 500.
