It's hard to say if this is normal behavior, as the oil rate of modern saws is a lot less than it used to be (especially Stihl). I normally use about 1.5 tanks of fuel to a tank of oil on most of my saws. My Stihls all have an adjustable oiler (screw on the bottom) and I have it maxed out. Even then, they don't sling oil off the bar tip like old saws did -- it's more of a mist now. This is intentional, to be more environmentally friendly. I have not run into issues with abnormal bar, chain, or sprocket wear, so it's obviously doing OK.
The only thing I can suggest is to make sure you are tensioning your chains cold. Tensioning a warm/hot chain will cause it to be too tight when it gets cooler, and can cause a lot of issues with wear on the bar, chain, sprocket, and crank bearing.
Also, make sure there is a healthy dribble of oil out of the oiler port when the saw is running on your bench without a bar/chain. If not, work backward to figure out what's wrong. Even today's oil-stingy saws should put out a healthy dribble of oil. If the oil flow is decent out the oiler port, make sure the bar oiler hole is clear, as well as the chain slot.
You can upsize the oiler on several pro Stihl saws. Not sure about Huskys, but I would doubt it on a 450, since it's a homeowner saw.
Sorry I don't have anything beyond basics to suggest.
