Well Corbon is always among the fps leaders, while not always among the performance leaders since ramped up fps does not always translate into better performance. But anyway, there are two that the manufacturers say are rated for 1250 fps. One happens to be the Corbon DPX 115gr +P (sorry) and the other is Winchester Ranger 127gr +P+. There may be faster loads out there, but these are the fastest loads that I would trust. FWIW, my preferred 9mm load is Winchester Ranger RA9T 147gr which only goes 990 fps.
