[QUOTE="Vettepilot, post: 1989399, member: 114372"] So, often times someone will ask, "How can an aluminum cleaning rod, being MUCH softer than steel, damage a rifle bore?" To this I try to explain that when iron/steel combines with oxygen, we call it "rust'. When aluminum combines with oxygen, we call it "aluminum oxide". Aluminum oxide is so hard it is often used as sand blasting media, and is sometimes used in making sandpaper as well. So yeah, it can definitely hurt a steel rifle bore. I sometimes get the feeling that they don't always believe it, and I wonder how many barrels are trashed as a result. Then not too long ago, I finally got my long desired bore scope, and like a kid with a new toy, I've been bore scoping everything within reach! Yesterday, I got around to my long suffering old Marlin .22 that I bought used many years ago. It never shot worth a dam, but I didn't care because it isn't used to shoot groups nor to hunt, it is only used for kids to knock over cans at maybe 50 feet. But when I bored scoped it.... WOW! I found out why it won't shoot accurately for sure, and it is a "Picture Perfect" (literally), example of what improper cleaning rod use can do to a crown. So I thought I would post some pics here for us to refer newbies or doubters to, and have a clear example. The crown is severely damaged on two sides, and you can just imagine someone pushing and pulling a cleaning rod in and out of that muzzle with great abandon!! Pretty dramatic! Vettepilot [/QUOTE]
