The voice of one who has had to remove stuck bore snakes (plus twist drills and drill rods and cleaning rods and dowels and....). Bore snakes of various kinds had become pretty much obsolete when non-corrosive primers came into use and it was no longer necessary to clean a bore within hours of firing it.
But in the last few years someone (I would curse his name if I knew it) promoted bore snakes as convenient (which they are) for field cleaning. Why a modern rifle firing modern ammo needs cleaning "in the field" was never explained but the makers of boresnakes promoted them widely and a large number of gadget-happy "hunters" bought them. And got them stuck in the bore. Some thought of shooting the obstruction our with a 1/2 charge and no bullet, which usually works. But, as always, if 20 grains of powder works, 50 will be work better and leaving the bullet in will be even better. So barrels bulged and blew. And the makers of boresnakes laughed all the way to the bank.
Just to add: During WWII, several armies issued cleaning kits consisting or a chain or cord to which a cleaning patch could be attached for emergency bore cleaning. The U.S. one was a cord, called a "thong" (put away your dirty thoughts!) which was carried in the butt of the M1 rifle in a plastic case which also contained oil. Smart GI's soon learned that the thong ALWAYS broke, leaving the pieces in the barrel, and the squad leaders started carrying cleaning rods. The abomination, called the "thong and oiler kit" was left alone and Ordnance finally came up with a jointed cleaning rod which worked well. Some complained that the jointed rod was hard on barrels, but it was softer than the barrel steel and worked quite well. It's descendants are used today with the M16 and M4 carbine.
