Where do you get the Balistic Coefficient for Sierra bullets? I don't see it in the Reloading manual....or am I just not looking in the right place?

It is but you have to look under exterior ballistics section or something. to easy to put it with the bullet I guess.

Never looked in a reloading manual..
But curious, Why would BC be listed in one?
Doesn't have anything to do with reloading.

The Nosler Reloading manual has the BCs in it.
The Hornady Reloading manual has the BCs in it.
The Speer Reloading manual has the BCs in it.
The older Sierra Reloading manuals had the BCs in them.

Before the world was populated with people who could not figure out how to draw a breath without looking on the internet, we actually had to read books written in ink on paper to get information.

Now you know how Jimm managed to communicate with Scott while hunting Oryx down at Area 51.

Obviously reloading manuals are no longer needed..

Thanks to the information age, we can look up about anything quickly. We have reloading software which can be calibrated to our barrels, and so we can predict in a minute exactly what a combination of components will produce. We can calculate BC and stability for the bullets & barrels in our hands, under the conditions we shoot. We can design cartridges, reamers, and dies on our laptops during lunch. We can review patents, including drawings, sources, and references. We can communicate in B&W using email with component makers, including sharing drawings and specs, so that we actually get everything committed to. With this, we can hold anyone accountable as appropriate.
And most important, we communicate in forums to share and gather specific information with each other.

There was a time in my life when I visited libraries atleast weekly. I had 20+ magazine subscriptions. I must have hundreds of expensive books in boxes.
I can hardly believe it now.

So yes it seems odd to me that people still buy books for reference, only to declare ambiguity..
