Fred Zeglin is best known for his line of “Hawk” cartridges and Z-Hat custom rifles. Lesser know is this treatise on the subject of wildcat cartridges. “Wildcat Cartridges", published in 2005, covers all aspects of wildcats. From the history & design principles to reamers & testing, and everything inbetween. He discusses throat design, shoulder angle, pressure, parent case choices and predicting results. 

If you shoot, want to design or just want to learn more about wildcat cartridges, I would highly recommend this book. A little difficult to locate, it can be found on Amazon & eBay from time to time.
