When using the shotgun, it has two modes of fire (regular shoots one shell, alternate shoots two shells). By pressing both fire buttons, you will shoot three shells, which in most cases is more useful. Try using this on groups or stronger enemies.





Loads of Shotgun Shells: 


Go and collect a shotgun but make sure it has more than 8 bullets, 
and fire 1 bullet only! Then when you press reload, he will bring the shotgun up then down a little bit to re-load. 
As soon as he brings it down a little bit start walking forward and he should load more than one shell. 
If he does not and only does a couple more than one, just press re-load and he will load the rest of them. 
Then just keep collecting shells and keep re-loading. This will take a few trys, but it'll work when you get the hang of it.
