    I have been loading for several years so I'm not a newbee but I will andmit to being a newbee with the AR.
    So here is my problem. I'm haveing problems with the AR ejecting my dummy rounds.
    All have been trimmed inside the neck reamed the mouth debured and full leanth resized with a Lee FL sizing die all the brass is RP brass. In setting up my sizeing die I have adjusted it with the ram all the way up and tightened the die all the way down and then added about a 1/8 of a turn down to make shoure of a full leanth resize.
    My AR is made by Armerlight with a 22" bull barrel it is there varment version
    I'm not haveing the same issues with factory ammo I'm able to eject them with ease.
    I'm leaning towards buying a small base sizeing die but though I would ask for some advise before spending the $$.
    Thank you

    Color a tight round completely with a black magic-marker or dry-erase marker.

    Then chamber it.

    Where the ink rubs off is what is tight.

    If you are crimping, you might be buckling the shoulder a slight amount and you can't see it with an eyeball.

    If not that, press flex is not pushing the shoulders back where they came from.
    Adjust the die down further until you get a definate 'bump' cam-over at full ram stroke.

    Thank you RC I will try what you suggest.
    Also I'm not crimping and seating the bullet at factory spec

    Additional to what RC said, check the case length.

    Case length is 1.750. 0.010 under trim length

    Clarification, please. Are you having trouble with ejection or did you mean extraction?

    Extraction would be a better way to explain it I guess.
    I loaded 3 dummy rounds (No powder or primer)and manually cycled then through my AR.
