Here you go
@Savagesteve maybe you just need change in your routine. Do conventional drop sets. Do mechanical drop drop sets.
Conventional Drop Sets: is men you load the bar and strip 10% after each set until you fail.
Mechanical Drop Sets: Set an adjustable bench to about 45% angle. Get 3 dumbbells that you can work through all theses sets with. Only rest you will get is adjusting the bench. Do three sets incline at about 45%. Once finished drop the bench down one notch and repeat same weight. Then drop the bench down again to flat bench, and repeat. It's a killer exercise and will get you a nice pump and tear up those muscle fibers to create growth.
Like other have said lateral raises don't have to be super heavy but have enough to create a stimulus. Same goes for front and rear delts. Strict Over head press with some moderate heavy weight will add some mass to those shoulders.
For me, when I am consistently adding the Arnold Press into my routine my shoulders begin cap.
Aslo chest flyes dumbbell or cable will build mass for most. Just see what works for you and run with it. Good luck.
