Rod,
Do you use standard Hoppes No 9 or the No 9 Bench Rest version? I seem to remember conflicting opinions on a US forum discussion about whether it is safe to leave the Bench Rest version in the bore during storage, and some even said the standard version shouldn't either. If you've been doing it for while without evidence of damage, then that would useful to know. Maybe others can chime in?
I have mainly used the Hoppes 9 and have left it in all of my good barrels for months at a time. It does dry out to a thick gummy consistency but has never caused any issues. I have left the Hoppes Benchrest soaking for a few days or weeks at a time as well without issues when viewed with the borescope.
I have tried leaving some Boretech solvents (eliminator and C4 carbon cleaner) soaking in some old barrels and the barrels rusted and pitted after a few days.
