Would going heavy on Military Presses increase my size

[godly_one]

i've always been told that i shouldn't go heavy on shoulders to prevent injuries. but then again, i'm not one that usually takes advice from others about working out. reading this makes me think i should go heavier because i am not happy with the results i've seen so far. i do like the dumbells more than the barbell though. seems like i'm hitting the stabilizers too. but maybe that's just all in my head. i could definetly do more weight with a barbell. any suggestions?
