Ammo and Class Ranges

In Call of the Wild the ammo, not the gun, decides what you can take: each load is rated for a band of animal classes. Use a load inside the animal’s class to pass the harvest check and keep the trophy.

Notes: Three-barrel drilling (shotgun + rifle), switch ammo; Falcon 3-9x44 scope. One guide shows 16 GA slug as 4-6/4-8; most sources 4-7.

How to Use the Grelck Drilling Rifle

• Switch shells to fit the animal: birdshot for birds and small game, buckshot for close medium game, slugs for bigger animals at short to medium range.
• With birdshot, swing through the bird and keep the gun moving as you fire; most misses are behind.
• Keep slug and buckshot shots close. Shotgun loads lose energy fast past their effective range.
• Carry two shell types so you can take whatever walks into a zone.
• Big game: it reaches class 9, so it can stop dangerous animals. Keep a follow-up shot ready on bears, big cats and buffalo.
• Small game: its lightest load covers class 1, so it doubles as a small-game gun without ruining pelts.
