Just make shure your shells are new and not banged up any especially around the rim area. I had a 1300 defender and sold it after finding out the hard way that the design of the bolt head area is finicky. I deer hunt with the 12-gauge and slugs and shells if there cycled too much in an out of guns like my 870, ithaca or mossberg will be fine in them but the Winchester it would lock the gun up and wouldn't eject out and had to go to a gunsmith. The gunsmith said this is a common problem with the 1200-1300 design. I thought that to be not good on a gun that is marketed as a security product.
