Does anybody out there know if there is a Web site that has the ballistic coefficient's for assorted casted Bullets? Now I was kind of hoping that I would not have to put the parameters in for each Bullet.

Quaken,

Lyman gives the BC for many of its bullets. Load From a Disk has a library of lyman designe and BC's for them, sometimes at three velocity ranges.

The truth is, ballistic coefficient isn't as important as most think it is. The only time it has any value for you is in calculating down-range ballistics. For the average hand loader it means nothing. In realityt, if you use a BC of .100 for pistol bullets, .200 for flat pointed or round-nosed rifle bullets, and .300 for pointed bullets you will be so close at reasonable ranges for the particular cartridge in question that it will make no practical difference. I have run many comparisons in LFD changing only the BC. For, say, a .45-70 with a flat nosed 350 gr. bullet, the difference in drop at 200 yds for BC's ranging from .150-.250 is usually only 2" or so. This does depend on initial velocity, but all other parameters being equal none of us would ever know the difference at normal hunting ranges.

If they are not listed by the manufacturer about the only way you can determine it is by taking two velocity readings over a known distance and plugging those readings and distance into a BC Generator (http://www.beartoothbullets.com/rescources/calculators/BC/index.html).

I am not aware of a web site but a few years back a really good article was published in Rifle. Wayne Blackwell and Milton Kitano co-authored it in the November-December 1979. If You cant find the article somewhere I could photo copy it for you. You might also check with the Cast Bullet Assoc, There is alot of reall good info there.

Good Luck: Leon
