Range XP from 45k Cannonballs?

I'm going to be training slayer with a cannon now, I have 70 Range at the moment and will be spending 10m on 45k Cannonballs. Roughly how much xp/what level will I get up to in Range after they have all been used?

Thanks in advance

 

I would say roughly 1.2m - 1.5m xp. It's far wiser to sell the Cannonballs and buy Red Chinchompas (if you're 43 prayer) which would give you around 3.5m xp.

 

Cannoning on a slayer task will definitely hasten your trips. 45k cannonballs will get around 1.2m ranged exp like jamesyy said.

 

One thing to note about the chins though is they might not always be the most effectively used in all your slayer tasks, personally Id use cannon.
