    How to slug a barrel?

    Just a simple question about slugging.

    I am just getting set up for casting. I have most of the things that I need which I have been buying over the last 6 months +


    Anyway I am ready to slug the barrel of my .454 and I am wondering if I need to lube a cast boolit first before slugging it or can i just use the straight lead unlubed boolit and drive it through?

    thanks

    You don't have to lube the bullet but you need to lube the bore with a good gun oil.

    I pretty new to some of this stuff too, but I just slugged several of my barrels lately. I used a soft lead round ball that was lubed up good. For my .45 I hit a .44 cap&ball round ball with a hammer some so it was a bit bigger and shaved off a little when I pounded it in the barrel.

    I can't imagine trying to pound an unlubed alloy boolit into a dry barrel; it would not be good, I think. If you do a search, there are many threads and tons of info here on exactly how to do it without damaging your barrel.

    I did do some searches and was looking for some stickies but I reallydidn't seem to find what I was looking for. (as far as lubing the boolit or not)

    maybe I wasn't searching the right phrases

    Here is a nice tutorial from 7.62x54.net (with pics), I use this technique with a 32 cal bullet. I lubed my bullet with Hoppes gun grease.

    I think I oiled the barrel normally with gun oil on a patch, put a coating of case lube on a soft, oversized lead ball, and pounded it through without too much effort. I went pretty slow and careful because I was paranoid about damaging the bore.

    If you look in the Stickies section of this form theres a link to a youtube video of it being done

    Don't over complicate it. Slugging is just driving a soft lead slug, larger than bore/groove diameter down a lightly oiled barrel. I would not use a cast bullet unless it was very soft and at least .010" over bore size. Just use something softer than your barrel for a driving rod (I use brass) and a large hammer (small taps will tend to swage the slug in the bore where a heavy hammer will be more of a push through the bbl.). Egg sinkers work well. I know it's scary hammering on your gun, just secure it in a good padded vice and be careful...

    For the revolvers, don't depend on just the vice, use some soft wood or whatever to provide as much support as possible. I cast a soft lead boolit for mine. The slugs were larger than the cylinders. I first used the to get a reading on the cylinders then used a couple for the barrel.
    For the autos, I just banged them through from the breach end.

    Thanks for the tips gentlemen,

    I casted myself a couple of nice soft lead boolits and let them cool nice and slow,

    lubed 'em up and gave the bore a nice coating of oil. Gently hammered them through using 3/8" hardwood dowel from the muzzle end and it went great.

    Calipers show .453 pre slugg measurement (unsized boolit)

    after slugging shows .451

    (my calipers are not the most precise/consistent tool) so I think it's time to inherit my NOt yet dead fathers Micrometer, when he is not looking.

    I have broke off a copper rod... The wooden dowel did not work... The barrel seems to not have the taper. Do you have any ideas???

    1/4" steel rod with a .25 ACP case hammered on the end that hits the lead. A couple
    rings of electrical tape and then a slightly expanded .223 or .25 cal bottle neck case front half cut off as a
    muzzle protector will NEVER damage the bore and WILL drive out the slug.

    NEVER USE A WOODEN DOWEL!!! These can and HAVE broken on a long angle and wedged so solid
    that the person had to make a brass drill to worry it out, all the while sweating damaging his barrel.

    This is NOT theory, it has happened.

    Alaksa girl, Don't forget to lube that 308 barrel with penetrating oil before going to next step

    Oh, and a ready source for round balls is as close as your stash of buck shot - I have several different sizes around myself

    and if your smallest size buckshot is too large you can roll it on a flat hard surface with a flat tool kept parallel to the surface your rolling against and that will oblong it and reduce the size.
