I have always loved Ithica 37 featherweight pumps (I have 4 of them), but had an incident this weekend that is giving me pause. We were shooting clay pigeons, and as I shot the first shell at a double, pumped back to reload, but before I could pump forward, the last shell in the mag came out and slid up the ejector tongs, and the primer hit the bottom ejector dog and went off. It caused the shell to explode, go back up the magazine and bounce back and impale on the tongs. It pushed the shell follower up the mag, and pierced it with the duck plug. My dad, the gunsmith, took everything apart and nothing appears broken, bulged, cracked or bent, but now I'm scared as he11 to shoot it again. I guess I was just lucky there wasn't another shell in the mag, and that I wasn't shooting slugs. Has anybody heard or seen this happen?
