Also of particular note: Wesley lays siege to the Fraternity fortress. With explodingrats.
During this scene, he shoots a guy through the eye, jams his pistol through the hole, and uses his body as a shield while continuing to kill.

And the final scene where Wesley lures Sloan out into the open with a decoy and shoots him in the brain. He then proceeds to break the fourth wall, asking the audience, "What the fuck have you done lately?"
Don't forget the fact that he shot it over several miles through cars and windows.
Not to mention that the bullet nearly hit both his former best friend and his boss on the way to Sloan.
More specifically the bullet passes through said former best friend's energy drink and the hole of a donut his boss is eating
