I started fresh and it took me 7 days to get my shotties.

Day 1. Bone>Two Bones. I played Die Rise a few times and got round 60, 35, and round 97. 20,000 kills 10 downs.
Day 2- Two Bones>Skull. Did town strategy.( I'll explain in a moment)
Day 3- Skull> Die Rise Round 60 and Played a few co-op games getting to 30+ each time.
Day 4 Skull>Knife Town Stategy all day and played a few tranzit games getting my bank points up.
Day 5-6 Knife> Town Strategy, Farm Solo
Day 7 Played a Online 4 person town with 3 randoms and I led the team with double the kills, 1 death, and 27 revives. Solo Die Rise round 23, xbox froze, restarted and boom had shotguns.

Town Strategy - Custom Game on Easy, start round 10 and PaP the starting pistol. Hold out at the Jugg stair case and Get 3250 points to open the door and buy jugg. Next Hit the box and hold out at the top of the bars drop off. Go for headshots and get perks as needed. If you're about to go down end it so you don't go down.

My Theories - You can only rank up once a day. A new zombie day starts at 6-7 PM CST.
The Talley's have nothing to do with ranking, just there to tell how many days you've played in a row. At 5 days you get blue eyes.
