I have had good luck with 4.2 grains of 700X, Winchester 115 gr. FMJ Flat Base Bullets, CCI 500 primers, R-P brass with a Cartridge OAL = 1.151" This is the max load given on the Hodgdon website. I have loaded this same Bullet with 4.4gr. of 700X and my Sig P 239 eats them up. But start at the lower end of powder weights and work up. I have used 700X in 9mm,45ACP,and 357 Magnum with excellent results, 700X is a clean burning good shooting powder that gets a bad rap because "it does not meter well" I gotten past that and use it a lot.
