I don't think that there is. I'm assuming that you mean sheet music where you can buy the actual parts that the orchestra played???
The only Metallica sheet music that I have ever seen has just been the books for guitar or piano, that Cherry Lane music puts out.
Some of the transcriptions in those books are better than others, but if you know the song well enough because you've heard it a lot, it's easy to work around a bad transcription. But for the most part the books aren't bad.
There is an S&M book that you can buy from
Sheet Music Plus But it's a guitar voice book. They have a sample of the music that you can look at online. However, with a little arranging you could arrange it for whatever instrument you'd like.
