good place to use a cannon on a pure?

i'm 68 range, trying to get to 75 so I just bought a cannon and some cb's, where's beat place to train with it? I'll be using knives while the cannons running, currently gunna goto rock crabs but idk if theres anywhere better...

 

crabs are good, even though it's tedious is a great place and easily accesible

 

as many places are much harder/impossible to get to on a pure

 

What's your prayer/hp level if your 43 prayer you should train at ape atoll skelleton monkeys you can get 68-75 in like 2 hours

 

You could try the ogre cage in the combat camp, south of Ardougne. That if you don't mind the fact you will not be able to pick up your knives. But since you are using a cannon money probably isn't an issue.

 

my hp is 58, prayer 1... I really wanna stay at level 1 pray as I want to do some f2p pking before I move onto p2p pking.
