    Does anyone have any tricks to decrease the inside diameter of a Mec powder bushing to decrease the powder charge? Thanks. Mike.

    If you are looking to decrease very slightly, I had a friend that painted finger nail polish on the inside of his bushings. Seemed to work for him. Jeff Rickert

    I use a small piece of black electrical tape,
    also clean the inside surface with alcohol to insure tape stays stuck. In 20+years of doing this I have never had the tape come loose.

    As inexpensive as MEC bushings are, it might save time and frustration to simply buy a couple of smaller ones. Just a suggestion. Regards, Ed

    I second the fingernail polish. Sandpaper and a dowel will open them up a bit if they are too small.

    Tape may come off.

    I buy bushings when they are on sale, and open up the next smallest size if it is critical. I am too impatient to wait for nail polish to dry. Most of my loads are on the low end so I accept a variation of .3 grains as acceptable.

    When loading high pressure 28 ga or 3" 20 ga, I use an RCBS Chargemaster and every charge is metered. For the couple of boxes a year I may use, I use a PW375 and do not drop powder.

    Why take the chance of having the polish erode away or the tape coming loose. The price of another bushing is not that much to be worth the risk. Get a narrow plumbers reamer go slow and weigh often. D Winter

    Aluminum tape works well and sticks like no other

    Mike, I use the finger nail polish and it will not wear away with powder charges. As most of Mec's bushing change around .6 tens of a grain of powder for each # up or down, its easy to apply one coat of polish or l l/3, or l 2/3 coats to get what you need if you go up one bushing. This way you can always remove the polish and still have a unchanged bushing if you switch powders a few years from now. Nail polish dries in like less time than a trip to the bathroom so waiting is not a problem for most of us. LOL. break em all Jeff
