Thread: Egg sinker size vs diameter

  1. #1

    Egg sinker size vs diameter

    Does anyone have a cross reference for egg sinker size vs diameter? I need to go buy some for slugging and would like to know the best sizes.

    this is why we have calipers.
    mine have accompanied me to the hardware store and the paper store,and the gun store.
    it's all an educated guess,,,, till the trigger is pulled.

    the more i find out about shootin boolits, the more it contradicts everything i ever learned about shooting jaxketed.

    I'm trying to avoid being the sketchy guy with the weird measuring device in Walmart...actually come to think of it, I get a feeling of pride everytime that I get a get a cross eyed look from an associate or shopper when I'm doing something like that...time to grab the calipers and run to the store!!!

    IF the sinker I am using is to big, I screw a drywall screw in the hole, attach the drywall screw to my cordless drill and put the sinker next to some 220 grit sandpaper. Trims it right down to size

    The 1/8 oz sinkers work up through 30 caliber and the 1/4 oz will work through 45 cal. If you are working at the upper end of the range you may have to give the sinker a rap or two with a hammer in order to make sure that it is large enough.
    If you get your shots in the black, the 10s and Xs will take care of themselves.

    If I've got an egg sinker handy, great. If not I cast a boolit from pure lead and cut it off a little longer than calibre. I then drill a 1/8" hole thru the center. If its not big enough I bump it up in a vise.
    Takes me longer to type it than to do it once the pot is hot.
    Some people live and learn but I mostly just live

    Sure here you go. Now keep in mind some will need to be flattened a bit to make them a bit wider. Not a big deal as a vise will do it or so will a whack with a hammer. I had to do that to widen the #8 to fit my 45 Colt and 45-70. The 9mm worked great with the one for 38/357

    Lead sinker sizes for checking gun bores

    Size 10
    For use in .270, 7mm, and .30 Calibers

    Size 9
    For use in .338, .348, 38/.357, and 35 Calibers

    Size 8
    For use in .41, .44, .45, and .475 Calibers

    The corresponding weights:
    Size 10 - 1/8oz
    Size 9 - 1/4oz
    Size 8 - 3/8oz

    If your sluging for strait wall grab a fired unprossed case, melt your egg sinkers in it and use your impact puller [you do have one right] and remove.
    Walla- bore slug ready to go

    220 grit sandpaper + lead sounds like a lap!

    I take my micrometer to the fabric store! I shoot muzzle loaders.

    I milled a couple holes in a ss block .01'' over each of my common bore sizes, then I cast up a pile of them. The empty cases is a good idea for not much hassle. I used to get 3/4 size for .40cal & 9/.38, then turn down to .008" oversize, can't remember the size for .45
    sent via hammer and chisel

    need oversized powder funnels , PTX's or expanders ? just ask, I make 'em for most brands plus my own styles.
