I've been looking into getting an m44, and one thing I noticed when researching is that the ammo is corrosive. What kind of cleaning will I need to do to keep the gun in good condition if I get it?
Wrap a chamber brush with a section of paper towel or cloth and wrap it around the brush and insert it into the chamber and rotate it about 10-20 times and it's usually spotless (this is after I have used the brush without the towel).
The same goes for the barrel. Mine shines like new. Even the corners of the riflings are shiney.
Always use a bore mop after using a brush.
Some gun oils are made to lubricate, others are to clean. Get a cleaner and a lubricant. Like CLP and Lucas.
The other way of getting an extremely clean barrel is slugging it with a wad of paper towel and various sizes of wooden dowls 1/4 thick and a rubber mallet. Get it nice and tight. I send about 3 through it and that usually pics up everything.
Clean as you would any rifle unless you use Mil surpus ammo! milsurp is corrosive!!
I just Run a copper brush thro all mine dipped in hoppes no 9 twice then clean as you would any other rifle..I think you will figure out what works best for you and your rifle pretty quick
