To be precise, it deals damage equal to 50% of the target's current hit points, unless their current HP is 1000 or less, in which case it insta-kills them. Bosses are slightly more resistant to quick-draws; their HP must be 500 or less to be insta-killed.
In the case of vanilla doom monsters, even the toughest non-boss monster (the Hell Baron) only has 1000 HP, and thus can be one hit. With a Cyberdemon, the first quick draw will deal 4000 HP/2 = 2000 damage, the second will deal 2000 remaining HP/2 = 1000 damage, the third will deal 1000 remaining HP/2 = 500 damage, and the fourth, since their remaining HP is now 500, will insta-kill.
Mods such as Colourful Hell or LegenDoom Lite, introduce non-boss monsters with more than 1000HP, and thus make one-hit kills harder to achieve.
