    Have loaded thousands of 223 and never had this problem.
    Once fired Lake City brass
    Expander is .221 diameter.
    Once fire ring clears the neck i can push the bullet in deeper by hand.
    Does RMS sell the 69gr without the fire ring?

    OK, I\’ll bite. What\’s a \”fire ring\”?

    I am also curious… \”fire ring\” is not a term that I\’ve heard in reloading…

    are you referring to the point where the boat-tail meets the bearing surface of the bullet?

    It is formed at the base of flat bullets, and is about .0005\” in diameter. It provides a better seal for the gasses when travelling thru the bore

    so what you call a \”Fire Ring\” I would call a \”Gas Check\”

    I am also using Lake City brass
    I have not run into the issue you are having

    my brass prep routine is to…
    decap
    anneal
    wash
    resize case bumping the shoulders back ~.002\”
    wash again
    neck size (Lee collet die)

    I also run my projectiles thru a Lee bullet sizing die prior to seating

    I wouldn\’t think we would need to run hundreds of new bullets through a sizer.
    But i like your way..Cant get an answer from RMS.

    I agree that it probably is not necessary to run new bullets through a sizing die.

    I got the Lee bullet sizing dies as an experiment to possibly salvage some pulled rounds
    I was surprised by the variance in the amount of force needed to size the rounds…

    Just for kicks I ran a box of new bullets through the sizing die and found that some slipped right through while others required a fair amount of force to go through… (a variance in the production process?)

    I use the Lee bullet sizing dies to try to remove some of that variance… (not so sure if it helps I do not separate the bullets by the force needed to size them)

    Jeff Siewert\’s book \”Ammunition Demystified\” addresses this a bit … when he covers the initial engraving force of the rifling on a fired round.

    I\’m still learning and adapting my reloading processes …

    Dad_Wil, I resize Zero Bullet .44\’s using a lee resizer before using them in revolvers. They typically measure 0.4305\” out of the box and I resize them with a .429 sizing die. They work great in my Marlin at the factory diameter.

    Are you lubing the bullets? I asked Lee and they advised applying some Lee case lube before pushing them through the resizer.

    4 a friend
    I\’ve done them with and without lube

    I size bullets as part of my reloading process because I believe I found a slight variance in the bearing surface diameter when I sized a box of bullets as an experiment

    I only size jacketed bullets to reduce any size variance in the rounds. (usually less than .001\” if it exists)
    I prefer to just run them without (no lube to wash off)
    I will lube if greater force is needed to size them

    I haven\’t done any cast bullets so I cannot speak to that (Lee does recommend their liquid Alox for cast rounds)
    RMR, Speer, Hornady, and Sierra make bullets better than anything I would or could cast

    Got around to try loading these shitty bullets….and the verdict is that they are crap and RMS got my money and won\’t respond to me
