Shocking, very shocking.
I used to clean up my CB's with balistol moose milk consisting of 7 to 1 water/balistol which i continue to date with great reliability.
Then after clean, i would spray to dripping with rem oil and wipe down for storage.
Now after cleaning i have been using straight balistol to spray down to dripping and after wiping down i store them.
This morning i happen to pull my 61 uberti and after pulling the barrel i glance down bore and just bout swallow my tongue ... i observe tons of dark crud in the rifling with some huge globs in a couple spots.
Going out to the shop shaking my noodle and wondering what the heck happened. I screw on the 35 cal jag and put a patch on and shove it thru the bore from the breech end to the muzzle. When the patch came out the muzzle , instead of the black gunky with rust on it, the patch had a clearish pudding gel on it. With the scientific sniff test i deduced that the substance was indeed balistol.
The important thing was the bore is spotless as was the cylinder chambers.
All in all the balistol did its job very well and the percieved bore rust was just balistol that didnt get wiped off when the straight stuff was saturated and wiped off the rest of the gun. I have every confidence in the balistol doing its job. Perfectly happy with this do all solution.
