Great information but the reading can get awfully dry. Reading Mann's book is what prompted my extensive testing, a man who continually lived outside of the box in search of the X error and way ahead of the times.

Mike click on the Articles Index and you will find some very interesting reading. Here are a couple of my favorites on primers. There are those that think primers don't make a differance and they can make all the differance in the world. The high speed camera work catching the Brisance really helps tell the tale. When you get to the small rifle primers I think you will be amazed by the Rem 7 1/2 Brisance compared to the rest and they are far from being mild and a surprise to those who use them after I shared this with them.

Google digitized the book several years ago.  I downloaded the pdf file and have it on my computer.  I've read it at least twice and as J Louis said ... it is quite dry.  Dr Mann took a given topic and tested it 20 ways from Sunday - great information though

In addition, there are many other BPCR books available on Google, by ... Mordecai - Noble & Abel - Metford, etc and including the testing of powders at Aberdeen and a couple of other arsenals 

Here's a book I bought because the information is concise and excellent ... The Art of Shooting with the Rifle by H. St. John Halford and an Illustrated Treatise on the Art of Shooting by Charles Lancaster

Dr Mann's book is worth reading. Slow and at times tedious, the items covered and conclusions are essential to understanding how bullets perform. Might read some obscure part never think about it for years. Then it becomes relevant to a problem you are having or result that could not be explained without the background from "The bullets flight"

It is definitely a useful and interesting book.  I've had the digital copy for a little while and just purchased a printed copy with Pope's annotations on ebay last night.

I've had and read Mann's book for years. I tried to synopsize/categorize/workbookize the tests and failed miserably. Some of it just doesn't make sense, what tests were done when with what gun and load/bullet is not clear. What's that short barrel no barrel bullet expansion about?
Can someone show me an example of test/s and conclusions that makes sense?

It IS indeed basic research.

The short-bbl test shows simply that the base bullet starts moving and hence expanding before the front of the bullet.
