What to with iron chins

Hi! I've been osrs for quite a while now, I started my iron a year ago. Got slowly 99 fm, now working on hunter till 99.
Now I've got a 40 melee stats 70 rang(mystic chinning cox 45-70) and still 15k chins left.
I love catching chins, can do it afk or full on 1T, did both way to much lol.

But I wanna use the chins to skip the 70's range lvls and straight go to 80 ranged, why? Because I feel like. I know it's good for Kree and a waste cus I don't have rigour yet etc.

Is there a place besides mm1 tunnels & temple spiders I could use the chins?
