Bounty Hunter Archive

I am not a very expierienced Bounty Hunter yet 5 losses for 5 marks.But I wrote a deathblow macro and have incapped Jedi;But I am ranged attacks with the 80 meter cyborg arms so distance is the key for me.But by the time I get close enough to deathblow they are up and full health again.I do not have a ranged Deathblow attack in my current template.

My question is what is the minimum Range for regular Deathblow?
