2 remington 1100 autos

i have 2 rem 1100 took apart cleaned and oiled put back now when you cock they want load. the shell just sits in the bottom.you can push it up from bottom and load with your hand but when shot does not eject thanks for any help

,,hello ,,will they cycle manually? and can you eject the shells manually,,if so.. it sounds like you have a part of the gas system either in backwards or in wrong place look here http://www.e-gunparts.com/productschem.asp? chrMasterModel=0860z1100 and make sure the gas rings #73+74 and the rubber O ring #12 are in properly and make sure the O ring is in the right place or isn't pinched or damaged ,, if everythings the way it should be.. it should shoot and eject,,but it sounds like it's not cycleing properly and that sounds like a the gas cylinder isn't sealing the gasses to cycle the bolt back ,, thats my guess if it will work by hand but not when fired ..
