Ditto: Find a standard 10 round hinged magazine, and put it on. With some practice, starting with a full stripper clip of 10 rounds in your hand, you can load a full stripper clip into an open action, and close the action, in 5 seconds. (The trick is to first press down hard on the rounds with the flat of your thumb, which will force about half the rounds into the action, and then put the tip of your thumb on the top round, with the left edge of your thumb butting tight against the clip, and the face of the thumb nail facing the left side of the rifle, and push the remaining rounds down hard, until the are all off of the clip and into the action.) Then, yank the clip, and pull back slightly on the operating handle, to let the action slam shut. This is much faster than trying to change out a loaded magazine.
