Anyone know where I can find a good database on the internet?
Particularly one with bullet lengths would be awesome.

Here is one but it's getting a bit dated. Perhaps someone will supply something better.

Some ballistic programs might have data such as coefficients. I don't think there is bullet length data available as it may not be a standard even with the manufacturer.

I appreciate it, guys.
Both very good links.
What I'm really looking for is bullet lengths, and any other physical measurements, e.g., ogee, meplats, boattails, etc.
Thanks again, though. Definitely worth a peek.

The Lapua manual is the only one I know of with (Lapua-)bullet length information.
"Quick Load" provides information, and "Load from a disk" as well. Unfortunately, LFAD's data are mostly wrong.

I compared the Sierra .308 dia 150 and 165 gr SBT's to the Sierra chart and they are exactly the same. I tried scaling them and got the same measurement within .001"!
