Ballistol
I have a positive story on Balistol from a month or so, ago.
I had an old rifle in my second safe, in the garage, that i havent used in 20 yrs well I inspected the bore and looked brown crud grew in the barrel, it was half the diameter, musta been corosive primers in ammo at last use.
I always run hoppies through after shooting anything, but this was crudded up from lack of cleaning for corrosives. I then cleaned as best I could with bronze brush and cleaners I usually use, like hoppes, breakfree, even pb blaster.
well opened it right up but still the barrel didnt look right, was gonna have it rebarreled, but a few weeks later I stop in to check out a new gun shop, get to talking with gunsmith guy about this, and he hands me a can of ballistol and a couple bronze brushes, and suggests I work the balistol and brushes.
I buy the can and brushes and couple nights later do the brush, let stand 5 or 10 min in between, brush few times more , let stand etc, while playing poker online one eve, and I get the bore shining new again, I mean I can't believe it, it realy softened the rust.
I havent put a bore scope in it but I can't see pitting or anything but shine all the way through.
well maybe I'm a lucky one, but I like this stuff, and will always pull some through after questionable ammo.
For lube in cold weather, and or long term storage, I will still use boeshield T9, this is good stuff for those who don't know.
I will continue to keep a can of this new found stuff around too.
