GIT overwrite a branch with the contents of another branch

Today I decided to nuke the contents of the dev branch in a project I’m working on. I wanted to reset it back to the last stable copy and develop from there. Rather than delete the dev branch I wanted to overwrite it with the contents of the master branch. To do this I discovered I needed to perform a “hard reset” with GIT of the branch with the contents of the master branch. For those of you who want to do this I have provided the details below:

$ git checkout <branch name>
$ git tag old-<branch name>-branch
$ git reset --hard <branch you want to use to overwrite>

Can you improve on any of the tips I’ve discussed here? If you can let me know in the comments.
