One of my 1100s will not feed the second round after the inital shot because the first hull was not ejected. This is a new purchase for me and when I tried it and found it did not eject the first fired round, I figured it needed a good cleaning. Boy, did it ever. I don't think the gun had ever been cleaned. I stripped it completely and it took well over an hour to clean it was so cruddy . Once I had cleaned it I reassembled it and took it to the range again but it still will not feed the second round. Once or twice it ejected the fired first round but at no time did it feed the second round. This was with factory Federal loads so that should not be the reason. For those with experience with the 1100, where do you suggest I start checking? Thanks.
