Re: Books on Ballistics
Rinker's book doesn't belong on the same list with the other three you've got listed here. Bryan's is the least expensive and probably the most relatable in terms of the average shooter, where McCoy's and Carlucci's are more in the vein of true textbooks. They're also both right around the $100+ mark, making Bryan's a real bargain. The stuff done by Ted Almgren and Bill McDonald in either the Sierra of Lyman manuals is also quite good, and something you may already have on your shelves. Depending on your background and what specifically you're looking for, I think "Hatcher's Notebook" by General Julian Hatcher is a grossly overlooked pearl that should be on every shooters bookshelf. Tons of info in there, including a great deal on exterior ballistics, as well as some fascinating historical insights. There's also a complete set of Ingall's tables in there so you can derive your own BCs the old-fashoned way; by pencil and paper. Personally, I think this is essential to understanding just how these figures are established, rather than just seeing what a computer pukes out with a given set of inputs. The Ingall's tables, incidentally, can be used virtually interchangeably with the G1, so they're still perfectly relavent to modern discussions.
Both Hatcher and Bob McCoy have since left us, and I don't know Carlucci. Bill McDonald and Ted Almgren are both close personal friends, but they rarely get to spend time on sites like this. But Bryan posts here fairly often and is very helpful in answering questions. Seems like that might be worth considering when choosing.
