Is this good plan?

So, im currently at 80 range and 94 magic and 1 def.

I thought that should i get ranged up at ranging guild?

Then with tickets id buy rune arrows and then alch those?

I need about 77.5k alches to 99 magic, how much tickets i need to get same amount of rune arrows?

1020 tickets = 50 rune arrows

Ill make like 150gp/alch profit with this method and very good xp. Thats currently prices.

Also, what do you people think that my ranged will be after this?

And yes, bots will be used.

 

The tickets aren't a good way to make money, it would be easier if you just made the money ranging moss giants.
