What are your picks? Love Clint Eastwood westerns as well as his other movies.
I would add
The Magnificent Seven to this and its battle at the end. Maybe, that is more of a battle than a gunfight as you have a bunch of people against another bunch of people like with
The Wild Bunch.
The Magnificent Seven (1960) - Rotten Tomatoes
Some of these clips are rather bloody.
