To the OP, you say you use brute strength...
With a sharp chain you should not have to apply any pressure (fine, maybe hardly any) to make the saw cut. Really pushing on the saw may help things go a little bit faster, so long as you don't stop it entirely, but it's not something you want to do all the time. It sounds like you may have been really straining when you were finishing the cut, which as you suggest ,made the damage a lot worse.
