One of my employees brought this in today. The .22 ammo looks pretty old. I noticed it's .22 long and not long rifle. I've never come across .22 blanks either. He just wants to shoot it up and I could bring in a S & W 317 and have at it, but I'm wondering if it's worth trying to sell instead of shoot.
People do collect old ammo. Full boxes will have the most value lose ammo not so much. If I had that I would try to sell it on Gunbroker. You will have to ship it to them UPS.
Maybe sell it as a hole lot. You never know.
Notice the label on the 22 Long boxes...Gamble Stores.
