    Ballistic Coefficient for Cast Boolits

    I would very much appreciate it if some one more experienced and smarter than I could lead me to either:

    1)- A listing of BC for cast boolits
    Or
    2)- A way to calculate BC for Cast Boolits

    Many thanks

    Castoff,

    For a method to calculate BC for Cast Bullets go to;

    www.uslink.net/~tom1/calcbc/calcbc.htm#casts

    Have Fun,

    JCherry.
    Many thanks for you good reply.
    That is a very detailed calculator.
    I will have to get on the learning curve ASAP.

    For LEE boolits, I found this text on their website:

    "Ballistic coefficients for our bullet molds are found below the picture of the bullet on our web site and in our catalog. Our Shooter program allows you to calculate any bullet through the use of reading velocity reduction over a given distance".

    For lyman and rcbs bullets there are ballistic coefficients in some of the loading manuals.

    What boolit are you looking to fin the BC for? Maybe someone can dig it out of a lyman or rcbs manual if for those makes. I have both lyman and rcbs manuals but they are not handy at the moment.

    Lyman Cast Bullet Handbook #3 And Lyman Pistol and Revolver Handbook #1 have that for the HG boolets used in the data. Pepe Ray
    The way is ONLY through HIM.

    Pepe Ray,

    thanks for the confirmation on the lyman manual. I could not remember what all boolits were in the BC tables.

    BC for Cast Boolits

    Many thanks to all . I appreciate the good info.
    I did not have a specific boolit in mind, but wanted to be able to better evaluate each one as I might want to use it. Still in the early "looking" stage and have not yet settled on one to use.

    Does anyone still make custom boolit molds..............at an afforable price?
    If any body has names and addresses on this I would sure like to contact these folks.
    Many thanks
