    I am thinking of attempting to bore slug my .223 guns. Has anyone done this? It is still the same process? Lube the slug, hammer it in with 6" dowel pieces of hard wood? I could only fine poplar that skinny and I am afraid it will get stuck and end up a mess. Any advice?

    Sure.
    1. Don't bother. There isn't any choice in .22 centerfire bullet diameters anyhow... unless you are shooting cast.

    2. If you just must, drive the soft slug in from the breech just far enough to engrave in the rifling ahead of the chamber and any erosion if you have fired it much, then drive it back out from the muzzle. Brass or polished steel in such a skinny bore.

    Mookiie what i did was used a fishing split shot with a brass cleaning rod worked perfect for me the split shot was soft as butter jus lubbed up the barrel and as you tap it through you can feel it grab the grooves and turn.

    +1on a steel or brass rod. Don't even think about using wood dowels.

    Why not use Cerrosafe? Same effect, less likely damage to bore. That's why it's called cerroSAFE.

    When done correctly slugging the bore with a soft lead slug will yield the true bore dimensions. You push a slug through the bore. The slug will now be a mirror image of the lands and groves dimensions within the bore. You measure the slug. This in turn aids the hand loader in selecting bullets or casting bullets for their loads.

    Is this an old Soviet or Imperial Russian .223 that has some obscure diameter? Perhaps a 5.45-223 wildcat that's popping primers when loaded w/ standard .223" loads? When the caliber's stamped on the bbl you're going to slug it b/c?

    I am slugging it because I want to try shooting cast bullets with gas checks, and want to determine if I should size to .224 or .225.


    CerroSAFE would be a good option except I am bore slugging all my firearms at the moment so I would need to get enough to do 30ish firearms. Can you recast the CerroSAFE?

    Yes.

    You can reuse it over & over again until it is all spilled in the cracks in the floor.

    Then you have silver cracks.

    Ah - makes much more sense. Subsonic 90 grns?

    No I am going to try 55 grns using a 1 Linotype:1 Lead mixture and take it from their. I have never cast bullets so starting with .223 is maybe a bit to advanced for me, but if it doesn't work I can always melt them down and cast some 357 or 40 presuming my molds show up by then.

    3000 fps seems kinda fast for lead? I don't reload, but are you gonna run these in a gas-powered gun?

    I do not think I will get quite to 3000 fps, and yes that is too fast for lead, but a lead/Linotype alloy with a gas check should be very accomplishable. I will update the fps I am looking to get when I have my data at hand.
