Point of reference. Smallbore rifle silhouette uses chickens, pigs, turkeys, and rams at 40, 60, 77, and 100 meters, respectively.
Including the bases....the animals can be templated off of a rectangle the following size (HxW), but the actual hit area is smaller. Turkeys are the most difficult to hit.
- Chickens 4"x5"
- Pigs 5.3x8.3
- Turkeys 8.6x7.1
- Rams 10x12
All shots are offhand with no supports allowed. It's really pretty easy to hit them on a bench or any rest. Offhand is completely different.
