I do it.

Once in a while, doing it showes me a large burr or "hanging chad" of metal inside a case, which I would otherwise not notice (unless the decapping pin hangs on it and causes a problem).

I don't really know what those burrs and chads would have done to accuracy.

But, when I shoot a flyer in an otherwise good group, it is nice to have the shortest possible list of potential causes to check-out.

So, flash hole treatment is something that I do on rifle cases as routine initial case prep.

For straight-walled cases that I can easily see inside, I just look and remove any unusual burrs when I see them.
