I've never had any ejection issues with mine. Also, something most don't realize until they handle one, the rear ejection give the action a ridiculously long travel. Aside from foreign debris, I don't know how you could jam the thing up. Picture this, with the bolt all the way back, you could stack a round in the chamber, and two more rounds nose to primer behind it, and still have room to shake it all loose.
Now, if you get a stuck case with torn rim, you're going to have to pop the pins and pull the barrel out. It is a pretty major disadvantage other guns don't share. Good news is I can pop the thing open pull a case out and reassemble in under 10 secs using either a knife or my multi tool. It's not that I've practiced a lot, it's just that it really is easy. As the RDB is my only rifle, I felt I should drill it.
I'm sure you could custom bend a pick tool that could be used to pull stuck cases out without disassembly, but you'd probably lose it before you needed it. A ram rod would make more sense at that point.
