Would be nice considering the app cost 3 times more than some of the other ballistic programs out there that do a little more.

Brian is not an employee of a large corporation, and all the testing is pretty much out of pocket. Pearls before swine, perhaps.

On the AB custom drag curve info, FANTASTIC! When?

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,

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?

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.

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
