I like NK chain/bar combos like Speedcut or the equivalent because of how nice they combine speed and durability. I wonder if anyone will ever try a NK 3/8 chain.Edit: A fast chain and a durable chain aren't mutually exclusive. Semi-chisel can cut quickly, and full chisel can be tailored to be more durable while maintaining speed.
When you say round out, are you hitting the side edges of the rakers? After setting the depthThats about where I like my chains for bucking hardwood; looks durable with a lot of meat. Also looks like you're getting a bigger bite with the 'C' part of the cutter and not the top, which is also my preference. I'd definitely take the depths down a stroke or two, then round them out. Make a few cuts, and as @huskihl said, if the saw isn't feeding itself smooth (cutting one-handed in a log is a good way to tell) under its own weight, take another stroke or two off the depths and round the top out again.

It works better than leaving them horizontal. Ideally they would be rounded or have about a 6–8° down angleGrinding the rakers at an angle may remove the need for rounding them of.
It may not look as fancy but it seems to work fine on about a half dozen loops I ground.

Untouched raker with a little bit of a flat spot from filing the rakers prior to me grinding it.
