When knocking out a raptor make sure bola it and stand far enough back that it can't snap at you the best way to knock it out is with tranq arrows or tranq dart bola it and then hit it with tranq arrows/darts to knock it out and to tame it
Step 2: throw the bola at the raptor (it might run at you, so do it quick)
Step 3: knock it out with tranq arrows (bring 10+ arrows)
Step 4: once the raptor is knocked out you can feed it raw meat, raw fish meat or raw prime meat (if the meat is cooked it’s even better) prime meat is the best meat you can feed it. Up this if it was useful.
Instead of using your bola on the raptor. How about letting your tribemate get pounced and get mauled by the raptor? The raptor is busy mauling tribemate how about using that as an advantage it just stands still now take your knockout weapon of choice and ta da!! KO sure your tribemember will be angry but a sacrifice will come at a greater reward.
If you see a pack of raptors then don’t get close. If you want to tame them, I suggest bringing a longneck rifle or fabricated sniper rifle with 50-70 tranq darts and a group of 10 dilos. After you found your pack of raptors, get the high ground and shout “it’s over raptors, I have the high ground” and open fire. Keep in mind, aim for the head. Up this if it was useful.
