      Making a pound cast
      A pound cast is a way to check the shoulder, neck, throat, lead, and rifling of your barrel.
      This is a very important for choosing a bullet design that fits your particular chamber properly.
      This is about the only way to get accurate enough dimentions of these areas.

      NOTE:
      Use caution in doing this and follow our instruction or you may be talking to your local gunsmith,
      or performing operations to get the slug out of your rifle that could really make problems.

      What you will need:
      1. pure lead
      2. brass cartridge case for your rifle
      3. hammer
      4. steel rod slightly smaller than your bore
      5. gas check for the caliber your rifle is
      6. bullet mold a little on the heavy side for caliber
      7. propane torch
      8. ladle

      The first step is to clean your chamber and barrel, and oil it lightly.

      Next, select a brass case that has been fired in your rifle and you don’t mind losing.
      Melt some pure lead in your ladle, and pour it into the case up to just past the shoulder.

      With your propane torch, heat the neck of the case till the lead melts and forms a level surface.
      This will anneal the neck of the case, and it also gives a good stop for the slug.

      Next preheat a mold, and cast a bullet out of pure lead. Flare the case mouth so that you can
      easily seat the bullet in the case with your hammer.

      Next, slip the cartridge and slug into the chamber and close the bolt on it.

      Take the steel rod. (1/4″Dia. rod for 30Cal. – so on) and wrap masking tape around it about
      every 1 1/2″ to 2″ to protect the bore and the crown of your rifle. make sure that the end of the
      rod is square and has no chamfer on it. You want a square end.

      Secure the gas check to the end of the rod. Use a dab of grease to keep it in place and insure
      that you get it started correctly.

      Next, place the GC and rod in the muzzle of your rifle, and tap it past the crown and down the
      bore. You will  feel it contact the bullet. Make sure you have a band of tape positioned to protect
      the crown of the rifle from damage as the rod is being pounded. You may have to remove the rod
      and add a band of tape.

      After you have pounded the end of the rod to make your slug you should be able to open the bolt
      and tap the “Pound cast” out. You may have to tap the rod as you open the bolt.

        Great tutorial Swede!
        One thing I would mention is that many people think that you have to wail on the rod and pound it till you wear your arm out and mushroom the end of the rod over.
        What happens is that they punch the rod through the GC and then they have a stuck chamber slug and a very stiff bolt.
        The trick when doing this is to remember that less is more!
        Think about it, if you don’t go far enough, you can always reinsert the slug cartridge and give it a few more measured pops with the hammer. No harm no fowl, but if you hammer the living pooty out of it, you’re going to have real big problems.
        It only takes a few taps with a heavy hammer fellers.

        BTW, great idea on starting this forum Swede, and thanks for having me!

          Good essential Info Al, a necessary job if you want ensure a particular mould is for you or need to input your needs in a group buy discussion.

          Personally I don’t use  gas check finding that a wad of kitchen towel works better for me.

              I fill a fired case with epoxy then slip a pure lead bullet in case. Epoxy will be squeezed out around bullet when seating, so just wipe away excess and let cure. Then chamber and pound away

                Well done should be much easier to do I’m going to have to give it a try and see what I can learn from it

                  I’ve pound cast a few leverguns satisfactorily.  But when I got my brand new 1885 Highwall, I tried to do a pound cast and I, obviously, whacked to hard with that hammer and it took me two days and a lot of sweat and tears to get the lever open and the cast out.  My lead was obviously not soft enough because I still didn’t get a good cast.  Frankly, I’m scared to do it again.  Sure would like to have the benefit of a good pound cast, though.
