So, a Finnish Tikka M91, 1942 made its way to me. Bought it, knowing it had a rusty bore, but the rifling is good, without many pits, and so is the crown. So, I have taken it home, and begun cleaning the bore. My regimen has been:
Put a fired case (from my other Mosin) in the chamber.
Spray some penetrating oil until its full.
Wait about 60 seconds, then drain, remove case.
Alternate a plastic and bronze brush on a mauser style pull through
Put a dry patch on the pull through until dry
And the rust has really decreased but there is still some rust. I have repeated the above procedure twice, is there anything I can use to dissolve the rust? Maybe Ammonia or Vinegar?
