I`ve also been able to get `em out, in one of 3 ways, usually - none of which involves stripping the chuck down.
1. As suggested by Batty - pull sleeve back, and shake drill whilst holding chuck toward floor.
2. Gripping with fine nose pliers / tweezers, pulling sleeve back, and teasing stub out.
3. Rotary stop, pull sleeve back, point at floor, pull trigger - ALWAYS worked if the bit was stubborn.
(except for the 4" core bit that I knaffered my SDS chuck with - didn`t snap, just wouldn`t release )
