Berger Bullets Tech Data List

Here is an amazing resource that Eric Stecker of Berger gave me when I asked him a question about bearing length and BC of some of his bullets.

You won't believe how much info is in this Excel spreadsheet that you can download and keep on your computer.

OAL
Boat Tail Length
Meplat Diameter
Ogive
Nose Length
Base To Ogive Length
Bearing Surface
Sectional Density
G1 BC
Recommended Twist

Thank you Len, for putting this resource on your forum. To save a few folks from rushing to conclusions, the dimensions listed are for reference only and may vary slightly from lot to lot. If you bullets don't match the exact dimensions listed it does not mean that you have bad bullets.

Regards,
Eric

Len, your timing is perfect. I just got home with a few boxes of Berger bullets for my 6BR and intended to look up some data on them. You just saved me hours at least.

Thank you Len, Eric, and Berger Bullets!

If all bullet manufacturers would provide such useful informaition handloading would be much easier and safer. I know of no other manufacturer who publishes reasonably accurate bullet dimensions. Few even give the bullet length.

Thanks Eric and Len.

I've been looking for a new Elk hunting bullet for my 270 WSM Winchester.
This rifle likes 150 SGK but hates 150 TSX.

Think I'll try the Berger 150s.

How does Berger determine their bullet's BC?

Calculations from bullet's physical properties (weight, dimensions, center of mass, etc)?

Time of flight between two screens at different velocities?

Just curious.

Bart,

The short answer is that we fire the bullets and measure their time of flight in 200 yard increments out to (typically) 600 yards. G1 and G7 BC's are derived from the muzzle velocity and time of flight data, corrected to ICAO standard sea level conditions.

You can read more (The long answer) on these two articles on our web log:

Take care,
