Agree with occasional + P use, but getting accurate fast multiple hits with a non-+ P round is a good goal.

Try posting a Wanted to Buy ad or look at the classified ads for the stocks, they are common and inexpensive.

Some are really obsessed about having not only 'a' box, but 'the' box (matching serial number, etc.). Since your chances of finding 'the' box are about the same as winning a lottery grand prize, personally I wouldn't worry about it. If you bought it from the original owner, contacting them to see if it might be in a dusty corner somewhere would be your best bet.
