Have had the same problem with my 38 spl --my own fault, of course. But trying to force the bullet back into the cylinder started to be a real hassle. So I found that by squirting some CLP down the barrel, letting it sit for a while, and then pounding the bullet back is MUCH easier.
BTW, I found some 1/4" brass rod that works well. The CLP also can make a wooden dowel work pretty well, too -- just be sure that it is large enough to pretty well fill the bore so that it doesn't spread out to make things worse.
