I got my copy last Friday. Read it over the weekend. My overall impression is very good.
Mike Venturino wrote most of the chapters which are easy to understand and does contain info of interest to experienced casters, but as others have opined the book is more geared towards beginning casters. Bryan Pierce wrote a chapter on lead fouling which I found interesting and provided a better understanding of reasons for fouling in revolvers. There is also a chapter on the physical properties of lead and lead alloys. Also included is an updated burn rate chart for powders in the back of the book. A cross reference provides top punches matched to individual bullet molds which I found handy also.
While there was a chapter on bullet lube, it was general in nature. I wish Mike had included more info on how to actually lube a bullet using a lube-sizer as that is an area that I have always had problems with. I just can never seem to get the lube-sizer adjusted right to lube bullets without making a mess. I gave up and switched to pan lubing as a result of my problems in this area.
In the load data section, all Lyman moulds are covered for each caliber, while normally at least 2 Lee molds, 2 RCBS molds, and 2 SAECO molds are included also. The new .327 Fed Magnum, 6.5-284, 30 AR, and other new calibers have data included. I was disappointed that some of the older BP cartridges were left out, i.e. .40-90, any of the Sharps Bottlenoses, etc.
As expected, the handbook extolled the virtures of Lyman products, but I did not find that a problem. All of the Lyman products I have used work well and as Lyman published the book that is to be expected.
For the price, I believe the book is worth purchasing, if for no other reason than the updated load data in the back half of the book.
