Dress your stone to get a clean sharp corner, side angle edge needs a sharp corner on top to work with.
The corner is still rounded, all dull material needs to be removed for a good sharp and self feeding chain.

It's something to do with the chains. I tried 4 or 5 loops the other day and all the same issue. Last night I pulled the one off my 036 and sharpened it, thinking maybe I was half asleep when I sharpened them or who knows and it still cuts the same.
Today I took that chain and put it on my 460 and same trouble. Unless that bar is goobered up too I don't think it's a bar issue.
If I push, it cuts ok. Depth gauges are at the correct height.

Looks like you went too deep and didnt get the top sharp . Try filing it higher and paying attention to get the top real sharp and pointed.I don't grind right or left in any specific order. I normally just start with whatever the grinder happens to be set at, or if it's a goobered up hand filed chain I pick the shorter ones to do first.
I adjust the grinder between right and left so they are the same length, depth etc... generally just a small adjustment.
I don't get super fussy on the grinding job, I guess we can call it a "woods" grind. It's worked just fine for a while, not sure what has changed.
Pics are a few different teeth, they are all ground the same though. Yes I realize the chisel corner isn't 100%. I normally get the bulk of them but also try to not remove too much material. Sort of a "bad habit" of customers getting upset otherwise when their cutters are 1/2 ground off to get it perfect.
Last pic is setup of grinders. Green one is the one I'm using for the cutters and the middle Oregon one is for rakers. Bar grinder on the far left (yes the wheel is about worn out, I'm getting my money's worth!)

And a test cutter of .404 using same grinder angles

It is a stihl wheel ,i think the arbor hole is different than oregon thoughwhat kind of wheel. it's pretty coarse, probably cuts cool.
I mill with round ,because i have not figured out how to get a 10 degree top plate on the silvey yet the usg does a nice job on the round though ,cuts almost as smooth as square ,but can feel a little more grab in it ,if you noticed i put "demo" in my description for the round the usg is normally what i clean the gullets with when do square .(I didn't think that Brian even looked at round ground chains . . . . !)
