Perfect Bison Pelt
How to get the Perfect Bison Pelt for the Legend of the East Satchel in Arthur's story in Red Dead Redemption 2.
You will need the rifle.
Time of Day: Daytime
Location: Heartlands, west of Emerald Ranch, they hang out on a hilltop just south of the train tracks.
The rifle is best for hunting bison. (I tried to use the bow with improved arrows, but unless I did something wrong that only damages the perfect pelts. I have not tried to rope them yet.)
