There's a hole in the forend iron on BSSs. If you put a pin through this hole, made of music wire or a small drill bit, the ejectors will not fire. No need to remove anything. Another thoughtful solution I've read is to replace the ejector springs with much weaker springs, that will lift the shells out far enough to grab them easily but not throw them out of the gun. On some guns, simply disabling the ejector firing mechanism results in the shells being lifted so little, out of the chambers, grasping them may be difficult.
