I am looking for a good guide on red chin hunting, because I am going to try and go from 75-99. thanks

Hm, it shouldn't be too hard. Just go to Monkey Madness or Bandit Camp, then buy range potions and prayer potions. A single trip should be enough to judge the correct amount of doses. As for equipment, get full void ranger and the Ava's Device, a ring with ranging increases if you have the budget. If you don't want to do Pest Control, do your best hide, etc.

 

EDIT:

Opps, chin hunting, my bad.

Do you know the boxing technique. You bring a bow and arrows, then shoot any surrounding red chinchompas. Once they respawn, note where one respawns and place traps in a + shap around the respawn. There are some spots where the respawn is blocked by a tree as well, that is better than a + trap, since you only need 3 traps. Then just shoot the chinchompa that spawned and it'll respawn and instantly jump into one of your traps. By the time you reset your trap, it'll respawn, no faster method.
