Agree with OldTimer1.
Suggest that dips are that much easier on the shoulder joints, pressing down and along side the body. Declines seems kinder to the shoulder girdle, also. Try DB's on declines, or any other chest pressing exercise. Allow a more nature motion for the pressing muscles. And better stretch. Try using a narrower bench width for chest work (there are different width's).
Even BB military presses hit the upper pecs, but not to the extreme that they would be considered a actual focus movement. Good Luck.
