Miller is saving me a lot of reading time, mostly because he is brief and to the point, and, more important, he agrees with me. Regardless of all this pressure and recoil stuff and a wordy dissertation on the workings of the Fox and Savage gun companies, Miller says it all in part of a sentence. "they just keep going on and on". In fifty plus years of high volume shooting and high volume gun buying, I have yet to have a problem with wear or damage caused by firing in a well maintained shotgun. End of story. Oh, not really the end. I use oil, not grease, and I have never bought a container of gun oil, use the stuff that comes in quarts at about $2.49 for enough to last several years, maybe decades. It's never failed me.
