Use a tranq dart and aim for the soft butt or head. Wait 5 to 10 seconds between shots, less wasted ammo, faster KO and less likely to kill. Easy to keep up with, kill everything on the ground around it to ensure a safe start. After KO add cakes and sleepy stuff (narcoberries, narcotic, or bio toxin) stand a bit away incase you are attacked so you don't kill it accidentally. I fly argy when taming snails since usually attacked by troodons and little thieves.
