5-8 Bleed Stacks on Critical Hit.
12-24% Rending on Enemy Weak Spot Hit for 3.5s. Stacks 5 times.
10% Critical Chance for every 0.3-0.45 second while aiming. Stacks 10 times. Discharges all stacks upon firing.
4.5-6% Critical Chance for each expended round in your weapon (resets on reload).
Last 3 points can be shuffled to different passives/talents as you see fit. I normally go swift certainty and 2 passives. You could go emperor's bullet into unremitting as well.
