I think if you are frequently cutting up on the ground fallen trees and reckon you dont get the bar stuck you are a bull shit artist, happens to everyone.
The tree is torqued, twisted and a mess, you think you're reading the cuts well but then something twists or moves, happens to everyone ... yes the new guys more often than the old but rather than yank on the saw trying get it out just tap a wedge in.
With the plunging technique of which you speak NG do realise that the reason the bar is getting stiuck is the wood is closing the kerf as you cut it.
I liken it to the compression on a palms head, rather than bore cut it and do the bore wing cut you'd be plunging it till eventually through ... there are better ways. One is multiple cuts so the wood closure isn't all on one kerf.
NG, whilst I admire your tenacity with this I do feel you like to get stuck with practices that are at the bottom of the evolutionary scale. We all started out where you are, plunging, yanking saws out, no wedges, no multiple cuts etc but for $10 a wedge is far better than fixing broken mounts on saws or falling ass over tit when it comes out and you trip on a branch backwards.
I know the ms660 getting stuck in a cut can shoot straight out and back at you like bitch, be careful, wedges are your cheap friends, if you dont have one cut one from the tree.
