It is completely user error.
One Shot is relatively expensive, 10 bucks for that little can. So folks think it must be used sparingly. The opposite is true.
You won't find many, if any posts here nor anywhere else that a user complained things went wrong when using too much One Shot, at least I have never read that anywhere that I can recall.
Shake it up well, spray it like it was free, and wait until the carrier evaporates. It is good up to big rifle, no problems.
I personally don't use it for much other than spritzing a bag of pistol cases(A tiny amount makes 9mm cycle like butter), because it is too expensive for me as a rifle case lube. I use pump spray lanolin based lube, it is cheap, but kind of sticky/messy, but not near as messy as a thing like imperial wax on a roll pad(I have used it, hated it.), I leave that stuff to people who are still in 1950.
