Picked up a Remington 550-1 a couple weeks ago. Got to try it out for the first time today. Was using shorts and long rifle. I got no fail to eject at all. But I got many fail to feed. Had more fails with lrs but shorts were not much better. Most lrs were dented in the center and some bent at the joint. I had some fail to cock. I think those were mostly with the shorts. In the one photo you can see a short fail to feed if you look close. Any ideas. Thanks for any help. edit It's not shown in the photos but most of the time the lower shell would be started in the chamber with another shell on top of it. If that makes any difference.
