A number of writers on guns have over the years latched on to a couple of men in the trade and shamelessly picked their brains . Now I'm not saying that this is true in all cases ,but I have know a couple of instances were a writer has been lead up the garden path. Whether it was that these men grew tired of constant questions or for sheer devilment ,some "tails" have been told. We have all heard of this story that a well jointed gun can be fired ,indeed proofed , the action being held closed with only a piece of string .Another related to the Hardening and tempering of shotgun barrels and another to the source of bone used to get the best colours . In fact one British writer was spun so many untruths , that he gave up writing about guns and shooting ,last I heard he was turning out gory sex and horror paperbacks. Point I'm making here Gents is that not all that is written in books ,no matter how well researched is always 100% accurate . Plus you have the books by Greener [WW] and Churchill who want to promote their guns, I'm sure there were similar in the US. Adverts were not always 100% honest either .
