Any way to bind a specific animation to a key?

I know you can bind the kill command to a key but I found that if you are running the end animation may not be what you want. I wanted to bind the heavy death animation for a sniper headshot.

I tried to import the animation but it doesnt end with him laying on the ground. I guess it uses that animation plus ragdoll for the end effect. I then tried to import that animation with ragdoll but that didnt seem to work no matter what blend I used (it would just reset him to a standing position it wouldn't apply the ragdoll effect at the end of the death animation)

Any ideas?
