I believe that the old CIL Dominion red box is a black powder load. (Please correct me if I'm wrong). As well, I've heard of stuck bullets causing rings with the old rimfire stuff. I bought a unopened box not too long ago and payed $125 for my collection. I've sold some singles at a show for $3 a piece in a heart beat. They may be crazy but I've seen some full boxes priced at $250. When you shoot these you will never get them back again.
I would keep some of the shells and the gun. Sell some of the shells and buy a cheap 22 for the kid, something he can shoot forever.
Here's a link to a black powder box of 32's I'am referring to.
