Would these work in the umarex T4E HDP.50? Or only the tr50 revolver.

Based on the loading mechanism on the HDP.50, I don't think it will work.

Whats the red thing around steel ball?. Got steel balls but no red things. What are they?

The red thing is a plastic sleeve that holds the steel ball in place to fire from a 50 cal air gun magazine. It fires as one piece. The steel ball does not separate from the plastic when fired.
