Search youtube for "insane range" and the first video in the results should be a video that shows a guy using chins on the skeleton moneys on ape atoll. I'd link to the video directly, but I'm not sure if that's ok to do, let me know if you have trouble finding it. The guy who posted the video claims that you can earn 220k to 300k range exp per hour. From what I understand, the chins used to hit an unlimited number of enemies in the area, but Jagex recently changed them to hit a max of 9 enemies. That said, I'm not sure if chins are still worth it. I understand your desire to get to 70 quickly (ranging fire giants is not quick) so if it's not a bother, I'd love to hear the results of whatever you end up doing (cannon or chins). that was a nasty video, but do you think chins are not worth it anymore because of their price? or because of the fact that you can only hit a max of 9 enemies. thanks so much for this btw this video is exactly what i wanted
