Incase anyone is wondering how quick draw is scored, it's based off time. To complete quick draw, you need to reach the specified score after you acquire all 6 perks. Once you do that, the mission ends. How long it takes you determines which medal.
The only times that ever popped up for me was 4:00 for platinum on mission 5, 3:45 for platinum on mission 8, and 4:15 for gold on mission 8.
For the latch kills, you could also play on easy and select mission 3. Kill the brown wolves at the beginning and let the white wolves attack. Only white wolves will latch. Cougars occasionally latch too, but the wolves are at the very beginning of the mission.
For the Mush, Mush, Mush achievement, if you're having trouble don't hesitate to skip the first sledding event. You'll go back to that exact same place later in the story and it'll be easier since there won't be falling rocks, falling trees, or a shakey screen.
