And for you folks that like math, Col. Townsend Whelen wrote two books that describe rifle shooting in detail. And I
do mean detail.
Volumes 1 and 2 of
Small Arms Design and Ballistics. IIRC the first covered interior ballistics (inside the chamber and barrel) and the second covered exterior ballistics (flight of the bullet). I read them both about 35 years back. Now Amazon shows them (used) at over $150 each
Being not too long out of engineering school, I thought I found a flaw in his physics math. Now, I sorta think I was likely wrong about that, since I can't remember what it actually was. Actually, there is much I can't remember from back then.
