The Bullet's Flight - F W Mann, 1909:

Old mate Rod pushed me towards this classic early ballistics book when commenting on one of my scribbles - Link:

- I bought a used copy from Amazon USA and it's just landed in the foothills of our New Zealand Southern Alps.

.. where I've started to read it - and I'm very impressed by the thorough records and inquisitive mind of the author Franklin Ware Mann (1856-1916) who grew up on a farm and started shooting at the age of twelve.

 He was intrigued by the spread of bullets fired at a single point of aim. He graduated from Cornell University with a Bachelor of Science degree in 1878 and from Boston University School of Medicine as a Doctor of Medicine.

 Verry interesting, - Cheers Rod,

I LIKE New Zealand (despite the bloody earthquakes).
