So i went shooting a week ago i was using '71 Russian surplus ammo about 40-50 rounds. After shooting i went home and tore her down. soaked the barrel in Hoppes 9 for about 5-10 mintuts ran some patches through until 3 came out clean. then ran an oiled patch down the bore followed by one dry one and put the mosin in storage. I got home from dinner last night and went in the cabinet to get out my sks so i could grab the firing pin out i just happened to catch out of the corner of my eye RUST in the barrel of my mosin. Instantly grabbed it broke out the cleaning kit and went to town bore brush 5 or 6 SOAKED patches with Hoppes 9 then ran dry ones through til i had 10 consecutive clean ones. i then ran 2 dripping oil soaked patches down bore followed by one very lightly oiled one and put it in the corner overnight. i havent looked at it yet to see if the rust has begun to return. Am i doing something wrong here with regards to cleaning the bore after shooting corrosive ammo???
