Like most of the advise so far, I agree it's possible but results can vary widely. This is mostly due to the rotational effect given the shot cluster i the barrel. The same effect spins the shot and centrifugal force does the rest. At shorter ranges it may indeed work for your purpose, 'short' being the operative word. Softer lead in shot will probably dirty the bore but shouldn't take more than a few more passes of a brush or cloth cleaning patch. Best advise is give it a try and see what the results are. Rifling depth will be the biggest factor most likely...you won't know till you give it a go! Good luck.
