I know the original question was to truncate the first 300 lines of the file but why do that when you could just solve the problem without modifying the original file at all. If the purpose is to not send the first 300 bytes to a command then simply use the tail command:

tail -300 original_file

So if you wanted to feed the original file to mysql you could use:

mysql < tail -300 original_file

( I'm a little rusty so man tail to find the exact command.) I'm of the belief of keep it simple. Why modify the file at all?

This idea wouldn't satisfy the original premise of the thread that the 
file couldn't exist twice:
Has anyone thought of using the shell command "split"?   I have used 
split or csplit to vi edit small portions of very large ascii files, 
recombining the big file using "cat".   It would probably not have been 
any faster than using "sed" as the original author did, but you might be 
able to do more complex editing.
