I have two books worth reading the first is probably the best all around gun book I've ever read. Boston Gun Bible BY Boston T party. I have bought about three copies of it and I don't have one.. every time I let a friend read it. I don't get it back....but that is OK... my deal I made to my friends was if you buy it and don't think it was the best general knowledge gun book they've read I'd buy it from them.. The second one I got recently was a very well written book about gunpowder GUNPOWDER Alchemy, bombards & pyrotechnics by Jack Kelly.. History of the explosives that changed the world.. get them they are worth your time.. B2B
