How much arch do you call Lobbing, most anything at 600 + is lobbing, maybe a little less, everything but a .50 bmg, or .416 Barrett, has significant drop at that range, the .338 Lapua, included, A ballistic coefficient of .450 to .500 at 3400 fps, still drops 9" or better, and that is as flat as it gets with firearms, and indeed is flat, with the proper zero, you would still have a 1/3 mil + to stay in the bread basket, 8". If you shoot NRA high power rifle, medium range starts at 600, long range starts at 800. And the velocity has dropped to 2300 fps at 600, still enough to do the job, that's like an sks at the muzzle. But it's not a laser beam.
