For a Perfect pelt, you need to find one that has a Perfect pelt, and make sure not to kick them, run them over with your horse or shoot them with either a rifle, side arm or shotgun, cause you will just ruin it, so Varmint rifle is better to use. And to get a Perfect pelt, you need to aim for the head so you won't get good or poor by shooting it on the body. That's all I could think of.
