I notice that the ejector on my 4 5/8 Single Seven allows cases to just clear the cylinder, so a barrel shortened by 7/8, I believe, will allow ejecting cases just barely enough to pick them out. I think any stuck case or fouled chambers would require taking the cylinder out and having tools to tap out the case. My gun has a Belt Mountain base pin, after throwing the stock pin a couple times, so if the short barrel had that too, sticky ejection could be quite a headache.
