That's a good set up for the long distance trial and error dialing in. Otherwise you're trying to hold your breath at the right times. You lose that if they're shooting back. Mine actually counted as offhand, as the sniper hit close to me and the suppression effect takes you off bipod.
If anyone is trying to get the 350m with the L96, the 2nd hotel on Oman to A is just over 500 and after lotsa tries on lotsa maps, thats the one I got it on. About 1 1/2 lines up.
