      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
