I just finished making 1600 rounds of 9mm 124gr FMJ, used Federal brass, CCI 500 primers, COL of 1.16" and 4.3 gr. of 231. Chronos at about 1050 fps from 5" 1911 and 4 3/4" XD. The speed you're looking for of 1150 fps is NATO standard and can be pretty hard on some semiautos, i.e. Hi-Powers. If you want to go that high I suggest a slower powder like AA#7 which has been my go to powder for NATO ammo.
