9mm loads

[MH357]

I have a fn and a taurus 9mm, both of which shoot 7 inches low at 35 yards with the winchester usa 115 grain fmj value box from wallmart. Winchester claims a speed of 1190 fps at the muzzle. My two reloading manuals do not list loads of 147 grain bullets. Both local gun stores only had 115 grain ammo. A heavier weight bullet will move the impact up but how much could i expect? Both guns have fixed sights and I would like to find a load to change the impact higher. Any suggestions other than changeing the sights? Thinking of order a box of 147 grain bullets and the 124 grain, I do not really think that their will be much difference in 115 and 124 grain performance wise.
