The single proved successful, charting high on many national charts worldwide. In the United States, it was Cher's biggest solo hit of the 1960s, peaking at #2. This was Cher's first top-three hit in the UK, charting at number 3. It would be her last top-three hit until "The Shoop-Shoop Song" 25 years later.
AllMusic's Joe Viglione reviewed the song positively: "Metaphors abound as the old world mix of strings collides with the new world of pop neatly edited into this under 3 minute hit..." Modern critic Tim Sendra, when he reviewed the "The Sonny Side of Cher" album, wrote a mixed review: "The only track that has any real zest is the Bono-written novelty "Bang Bang (My Baby Shot Me Down)," the kind of dramatic song Cher could knock out in her sleep but also a song with no real heart." In 1987, Cher recorded a rock version of the song for her comeback album Cher which was released as a promo single only. The 1987 version was performed on Cher's Heart of Stone Tour (1990), Living Proof: The Farewell Tour (2002-2005) and Dressed to Kill Tour (2014).
Also in 1966, Nancy Sinatra released her version of the song on her album How Does That Grab You?. It featured tremolo effect guitar (played by Billy Strange) and melancholy singing. This version remained relatively obscure until it was used in the opening scenes of the 2003 movieKill Bill Volume 1. This exposure caused Sinatra's version to be the one chosen by Audio Bullys when, in 2005, they used a sample of the song for their top ten UK hit "Shot You Down", credited officially to Audio Bullys featuring Nancy Sinatra. Canadian rapper Kardinal Offishall also sampled this version for his single "Bang Bang", which appeared on his mixtapeKill Bloodclott Bill in 2004. Rapper Young Buck sampled Sinatra's version on his song "Bang Bang" from his album Straight Outta Cashville. Rapper MMJC sampled this song for his track "C-Town Beat Down" on his album "Teaser".

A portion of this song version was also used in Netflix original TV Series Lilyhammer Season 2 episode 8.
