Bucks sitting flat on the ground or close to it, are my nemesis for getting the bar stuck. Average once per day or so. I never use a wedge when bucking.
My take is that a better sawyer will stick the saw less, but not "never".
I think that a bucking wedge or two can allow you more options, and can actually lift a log off the ground, at times, allowing the cut the progress through, top down with gravity. I usually use two or three long wedges. I can hold the narrow tip of one wedge and swing the heavy end to tap the wedges in, with surprising ease and efficiency. If the wedge is rotating at your finger tips, and the top end is moving reasonably fast, you often don't need to have a pounder (I don't like carrying around my 5 pound maul, which I use as my "gentle persuader".)
Maybe you know all this, maybe it will help.
Jerry B. talked about a reaming cut. Maybe what Blinky alludes to???
This is very useful. I you are cutting into a top bind, and keep working your saw in and out, reaming the cut, you are effectively plunging in, keeping th kerf kerf-width, with the top of the log closes the kerf to zero. This serves the same function that the wedges do in the top-bind. You can get the effect, without having to go get the wedges.
