Acquired this saw through a trade and will be used for bucking large oak mostly...I realize it's a bit large and heavy for this application, but it's what I have.
How aggressive can I go on my rakers? 30, 40, 50thou?
Read about 6° raker "progressive depth gauges" & FOP (Carlton File-O-Plate).
Old threads by BobL & Philbert
.. Are FOP really progressive depth raker generators?
If you don't find I'll lookup links.
Below is a very helpful recommendation. Easiest solution.
Sierra99 (AS, 2010) -- An old but good thread. It turns out that if you divide the gullet length by 10, you get the required raker depth to produce a 5.7 degree angle.
For example, a new chain with 0.25" gullet, divide by 10 you get a raker depth of 0.025", the "standard", that yields a good 5.7 degree angle.
If the gullet is 0.40" long, dividing by 10 gives you a raker depth of 0.040" (for the same 5.7 degree angle).

Edit... more.
Didn't answer your question. Right. Ms880 will pull huge. Just that at some point is dangerous & may damage bar rails or chain.
Read what Philbert references in old post. Good info on chain cutting action & wear effects.
