Funny you couldn't dump the empties out? The CAS shooters do it all the time with their SxSs. You just open it and jerk it back smartly and they usually pop righ out. I personally prefer extractors over ejectors especially for hunting so I don't leave empties all over the farmer's field or outside the waterfowl blind.
You may want to consider gloves similar to the Arctic Shield System glove. Its a thin inner glove with a heavy outer glove that folds back to expose the fingers and also the thumb if you want to.
