    It is just a cylinder with a cross hole or two and a couple punches. The cross hole will need to not be covered by the punches.

    Yeah and I’d relieve those bleed holes too. I’m getting ready to make some dies too. Anyone have a magical number and size of hole?

    For 223 bullets from 22LR brass .187, using factory jackets about .150

    1/16" diameter bleed holes, relieved slightly with a 3/32" counterbore.

    For .308;Lead Extrusions from Bleed Holes on my Corbin Lead Swage dies are 0.052 inches. Should give an indication of the Bleed hole size. Cast cores are 0.215 inches; and after swaging the cores are 0.225 inches. My Jackets are made from 5/16 tubing.

    For .223; do not currently have any extrusions (Have to cast new cores for the .223 in the early spring). So I can not measure hole size (but pretty sure it is slightly smaller) Cast cores are 0.185 inches; after swaging the cores are 0.191 inches. My jackets are made from .22 Short, .22LR, 22Mag and .17 Mag cases.

    Cool thanks Rick! Can I assume a slightly smaller bleed hole would be acceptable if you were swaging lead bullets? I would think a smaller hole would allow the bullet to form more fully to the shape of the external punch as it bleeds off the excess lead?

    Those measurements are from Corbin "H" & "M" style core swaging dies. Those are the diameters I use when making my own core swaging dies.

    I made one for my .204 ruger and used a 1\16" drill hole relieved and it works fine.

    Can someone tell me your method or drilling, reaming and honing / polishing the internal of the die?

    On a lathe I would go about it the following way. It would be 2 operations. First side would be the top of the die. Face, turn OD the entire length of the die. Drill undersized halfway through. Part off. Flip part and make sure it’s running true to what you already machined. Face to length. Drill undersized half way. Turn OD and single point threads. Qualify bore with a small boring bar as far as it will go into the drill hole, making sure you are still undersized from your final target dimension. After you qualify the bore, send your reamer through. Be sure that once again, you are still undersized. At this point you can polish with brass laps to get your finish about where it needs to be, but your diameter still needs to be undersized. If the reamer leaves a good finish then your probably good to go to heat treat. After heat treat, finish polish and bring to size with brass laps and diamond paste. This is how I’d do it If I just had a lathe and some brass laps.

    Ideally you want to cut the threads, qualify your bore, and run your reamer all in the same operation so those features are all concentric.
