I'll agree that it is a great book (the only kind Cooper writes) and well worth the price. If I were to quibble, I would point out that some of the B&W photos are a bit "contrasty" and do not illustrate their subject as well as they might. Also, I differ with Cooper on the proper management of the lever-action rifle. Cooper advises that the rifle be carried chamber-empty and that the lever be worked, thus chambering a round, as the piece is shouldered. I contend that so doing causes a lot of unnecessary, game-spooking noise and, if the shooter chooses not to shoot, it obliges him to a good bit of fiddle-farting with his rifle to return it to the chamber-empty carry state. I contend that lever-action rifles ought be carried with the chamber loaded and with the hammer in its safety notch (this is not an unsafe "half-cock" notch, but a true safety notch). Carried thus, the hammer is thumb-cocked while mounting the rifle.
Cooper is a dyed-in-the-wool bolt man...having cut his teeth on the Krag. On the two occasions I've been in his armory, I do not recall having seen a lever-action rifle.
