With the bonus damage its a 4 headshot kill at NL Shadow speed, it can tear through people. But you gotta be careful when you use it, cause if you are being fired one while using the bonus damage you die very fast. I combined it with a sidearm and used the sidearm like a primary and used the ToM to take people out at a range or who I got the jump on. It was very hit or miss on how well I did in a match with it lol.
