My SBH did the same thing about a year ago when I was target shooting out in the desert with a co-worker...shot a cylinder load...walked back to the Jeep to dump the empties and reload...and sure enough....no ejector rod housing...Walked back over to where I was shooting from, and VERY luckily...between the two of us...we found the spring and the small screw. Blue Loctite on that screw now.
