Sweep it up - off the floor of your local range....
.45 acp is one of the most durable cases out there..../ I can't tell you how many times I reload a case --- and the only reason I reject one is if it looks really nasty after I clean them....or mostly I just lose them, because they bounce all over on the concrete floors at my range....

Now, if you were looking for something like 10mm....I'd be more careful about picking up range cases...in a high pressure case like that....but .45 acp is easy to find.
