I use a small diameter laundry line cord, soaked in oil,
to clean my 22LRs, feed a string from the chamber side,
and pull the rope through the barrel once, it picks up gunpowder
and leaves oil.
Noo need to show your gratitude, for my pioneering another
way to save heaps of money on barrel cleaning, the satisfaction
of helping is thanks enough.
I'll be here till Thursday...
