The Ackley books Vol. 1 & 2.

Wolfe Pub. used to have Wildcat Cartridges Vol. 1 & 2. Maybe they still do?

Also for the technically minded Wolfe's Firearm Pressure Factors is interesting reading. Lots of equations, but still a good read.

JJ Donelly's Manual of Cartridge Conversions. Also Ken Howell's book on design & case forming is available again. Huntington's had it last time I looked.
