On the advice of several friends, I've made it a habit of running a Bore Snake through all my guns prior to leaving a range after a live-fire sessio n. With autoloading pistols, the correct way to use the Bore Snake is to threa d it through the magazine well first and then through the chamber and ultimat ely out the muzzle. When it is pulled through, it will thus scrub the feed ramp, as well as the chamber and bore. Threading it through the ejection p ort, as illustrated in the printed instructions, is an inferior method.
Running a Bore Snake through the barrel is, of course, no adequate substitute for thorough cleaning, but it does get the bore and chamber scrub bed free of the residue deposited there during firing.
Later that same day, if there is a shooting incident, and I am not involved , I can easily prove my weapon was not fired, as examination of it will clearly show that the bore has been cleaned since the weapon was last fired . Conversely, with the afternoon's residue still deposited in the bar rel, proving that I did no shooting will be more difficult.
Accordingly, make it a habit to always leave the range with a clean bore an d chamber. With a Bore Snake, the necessary cleaning can be accomplished is a few seconds. It is time well spent!
