Re O'Connor, I have his "Shotgun Book" and refer to it on occasion. I will say that Jack and his copy editor made one pretty glaring goof in the text, where it stated that there were never any LC Smith .410's. Jack was around when they were still making Elsies and should have known better. And speaking from personal experience--both books and magazine articles--it's great to have an editor who knows your subject. But with guns, you can't always count on that.
Drew, thank you for deleting and posting the link.
