my chevy has only gotten two pheasants and a dove this year
have you ever noticed that pheasants like to fly under not over the truck?
try different chokes. if your shooting 8's or 7 1/2's the load isn't the problem. everybody's different. i could grab somebody Else's gun that they hit anything and everything with, and not kill a single bird. i like full chokes and shooting birds farther out there. currently I'm using a extra full turkey choke in my browning gold. Ive switched out the chokes in the past that only lasts for about a box of shells, then i just put my extra full back in.
so my advise keep changing chokes until you find one (or in your case two) you like.
I don't try to offend....some times i get lucky!
