What is the easiest boss to solo range? and what would the minimum stats be for said boss?

I have solo'd Armadyl but I could only do ~3 kills per trip. I would suggest getting your range level up a little bit higher if you want to solo the GWD bosses.

 

I have seen people on YouTube solo Bandos while using range but I don't know if it's a viable method. I would think with your melee stats you would just melee it.

Saradomin is the easiest to get multiple kills once you know what you're doing (or in other words if you're not an idiot).

 

Armadyl is easy in the sense that all you do fight and eat but it is hard to get 10+ kills without max gear and stats.

So what would be ideal min levels to start soloing any of them?
