Interesting, I've had the same problem.
Bought an ms461 that had a nearly new but butchered chain, the cutting edges had been bevelled off for some reason and the rakers were not touched. I had the .325" 2-in-1 and liked it so bought the 3/8" version, took quite a lot of material off to loose the bevel and it was terrible, grabbing and bogging down, exhausting to use.
I put a new chain on in the end which transformed it, so I measured the rakers and they are 1.0mm / 0.04" so that explains that....... The chain is now probably not worth recovering.
I measured the .325" chains that have had many sharpenings,
Oregon .325 semi chisel = 0.4mm / 0.016
Stihl RS Full chisel = 0.7mm / 0.027"
The .325 is the Pferd, the 3/8 is Stihl branded
