New Applied Ballistics Book Features Test Data for 400 Bullets
Applied Ballistics has just announced Ballistic Performance of Rifle Bullets. This new book is chock full of “mission critical” data on hundreds of popular projectiles. This latest reference book from Bryan Litz contains live fire test data on 400 modern rifle bullets. The data pages contained in this book are similar to the 225 bullet data pages found in Applied Ballistics for Long Range Shooting. The Ballistic Coefficient data is based on live fire testing methods which are repeatable within +/- 1%. If you’re looking for “rock-solid” info on the ballistic performance of today’s most popular rifle projectiles, this work is the definitive print resource. Scroll down to see a sample page from the new book.

More about the Book
“Modern rifles have reached an unprecedented level of accuracy. In many cases, the weak link in the chain of hitting targets is the trajectory modeling, which is based on bullet performance,” stated author Bryan Litz. Unfortunately, shooters can’t always rely on advertised Ballistic Coefficients (BCs) being accurate. Slight errors in BC modeling can be the cause of missing your target. Furthermore, a meaningful apples-to-apples comparison of bullet performance is not possible when the BCs are determined differently by various brands.
This book provides highly accurate ballistic performance data for 400 modern long range bullets from .224 to .408 caliber. By employing a common testing method for bullets of all brands, shooters are provided with consistent and accurate performance data which can be used to compare and select bullets, as well as to calculate accurate trajectories which put your shots on target at long range. It is claimed that the BC data is accurate (and repeatable) to +/- 1% for all bullets tested.
Detailed stability data is also included which can be used to determine suitable twist rates for bullets in various environments.
NOTE: This is a reference book which contains mostly data pages. There is a single chapter in the beginning which talks about how to use the data. For a more thorough understanding of the science of external ballistics, readers are referred to: Applied Ballistics for Long Range Shooting (2d Edition).

Great that Bryan Litz has added more measured bullet data to his previous book.
One has to get used to the new format of representing the data. I personally miss the 4 CD values given previously.
Does anyone else think this is just a repackaged version of his original data to pull another $50 out of everyone?
Ed,
The data for many of the original 225 bullets is mostly the same with the drag data re-formatted. Some of the bullets have been re-tested and have updated results. However, the additional 175 bullets, including two new calibers (.375 and .408) *is* new (never before published) data.
The reason for this book is to have a place for just bullet data, so that further editions of Applied Ballistics for LR Shooting are not necessary each time there’s new bullet data.
This new book is planned to have future editions as more bullets are tested and old bullets are updated, sort of like a reloading manual is updated when new powder and bullets are available.
Take care,
-Bryan
Thanks for the new book Bryan. I definitely value the new information and appreciate all you do to help us shooters.

Bryan:
This looks like a perfect opportunity for a change-data-only subscription where those that purchase the new book can then purchase JUST the updated info each time new data becomes available – rather than an entire additional book. $50, discounted, is a lot of money!
Thanks for your consideration.
Bryan:
How does this new G7 data compare to the “custom drag curve” data included in the AB Kestrel? Seems you would have been able to obtain or derive the custom drag curve data from the testing done for this book – such that Kestrel could be “updated” with that data for all these new projectiles. Is that “coming”, as a for-free or “subscription” for those that have purchased your app or AB Kestrel?
As a target shooter I have maybe 5 or 6 projectiles at the weight I want. Test shooting brings this down to two or often only one. Unless there is a means of fine tuning the projectile itself (and I mean way beyond blind and wishful pointing systems) I see no advantage in a larger bunch of numbers on an already narrowed choice.
ELR Researcher,
We considered many formats for publishing the bullet data including what you described. In the end, the logistics of tracking who bought what, and how to disseminate partial information were too complicated. We chose the simplicity of providing a ‘latest complete edition’ for a number of reasons. For example, it’s the same model that most reloading manuals follow, and this book is a similar type of reference.
you’re correct about the cost being a downside of this approach. However, I’m very well know for sharing test data freely to individuals who ask for it. So if you purchase a book (or not) and would like my test data for one or two recently tested bullets, simply ask and I’ll provide it for free. Although I’ve got literally over $100,000 invested in creating this book, I understand that $50 is a lot of money to pay for a shooter who just wants one page.
To answer your other question about custom drag models, yes, all Applied Ballistics software products will be updated with the expanding BC and Custom Drag Model library. In the case of apps, updates will be pushed automatically for free. In the case of the Kestrel, the PC software tool which contains the BC and Drag Model libraries will be updated with the expanded library and available for users to download for free.
So the book is a stand-alone resource for bullet information, but the same information is also pushed to the Applied Ballistics software products.
Eric B,
The information presented in this book can be used in many ways. It can help you decide on what bullets to consider for testing which might narrow your testing down.
You do bring up a good point about bullet pointing though; it’s not always clear how much pointing will improve BC. This is one piece of information I’m considering for the next edition, but that will require re-testing everything to get the ‘pointed’ BC. Typically you’ll see 3 or 4% improvement, and sometimes as much as 8 or 10%. That’s a big range and unless they’re tested, you just don’t know.
Take care,
-Bryan

On the AB custom drag curve info, FANTASTIC! When?
For a group of people that only a few years ago had access to NO independent, test-produced data, I find it amazing that we have become so jaded, so quickly.
Brian is not an employee of a large corporation, and all the testing is pretty much out of pocket. Pearls before swine, perhaps.
So how about updating the bullet library on your smart phone app with these new bullets.
Would be nice considering the app cost 3 times more than some of the other ballistic programs out there that do a little more.
