LYMAN bullets` Ballistic Coefficients

[DARTH 44]

I like calculating downrange ballistics for various
gun-cartridge combinations(you can learn really interesting
things when you compare the data).
I`d like to do some ballistics for several BP cartridges,
but to do this I need Ballistic Coefficients.
Can anyone tell me where on the Web or on TFL could I
find BCs for the following bullets?:
-300grains Lyman#415175 for 40-90 BULLARD
-365grains Lyman#446109 for 44-77 SHARPS & REMINGTON
-350grains Lyman#456192 for 45-75 WINCHESTER
-405grains Lyman#457124 for 45-90 WINCHESTER
-500grains Lyman#457125 for 45-120 SHARPS
-450grains Lyman#515141 for 50-110 WINCHESTER
Plus:
-550grains Lead .451'' bullet for 45-110 SHARPS
-385grains Lead .446'' bullet for 43 MAUSER/ 11mmX60R
-337grains Lead .403'' bullet for 10,15mmX61R JARMANN
-285grains Lead .389'' bullet for 9,5mmX60R TURK.MAUSER

Any help will be appreciated

There are many BC calculator programs out there. A Google search using 'ballistic coeffecient calculator' came up with many pages of information. Also www.snipercountry.com has a good section on ballistics.
The Lyman Reloading Handbook has some of the information you're looking for. I have an older edition (46th edition) and it lists only (numbers listed under Centerfire rifle cartridges and not under black powder guns BTW). Perhaps a newer edition has more numbers;
#457125 weight-464 Velocity Boundaries; upper1600 lower 1200 BC Values; high velocities .391 intermediate velocities .380 low velocities .380
#515141 weitht-422 Velocity Boundaries; upper1600 lower 1200 BC Values; high velocities .250 intermediate velocities .250 low velocities .225
There is/was a book put out by Pachmyr called Extended Ballistiics For The Advanced Rifleman by Art Blatt that has useful information in it. IIRC soem of the other reloading manuals have the BC information listed in the reloading pages.
Just remembered I also have the Lyman Cast Bulet Handbook which is an even better source than the first Lyman book;
You may also try contacting Lyman direct. They can be found at www.pachmayr.com

Oh,yes!
When I was doing a search on this forum,I saw someone`s
question about calculating the BC of a round ball.
Well,for those who are interested in the subject I can
