Picked up a M96 Swedish Mauser (Garl Gustafstad 1917) today. I now am back in the 6.5x55 bid'nis once again! The bore is very good, will need to scrub for copper removal. I also had to take off some light rust off the bolt, receiver, and barrel. I used Remington Wonderlube and 0000 steel wool to remove it.
Outers has a copper removing foam that I am using with a lot of success to date. You pull the bolt, insert a tube into the bore, spray until the bore is full of foam, and wait 15 to 30 minutes. When the foam turns blue, push out with a dry patch. It turned a navy blue coming out of the bore after 15 minutes. I will continue to use this until the patches come out white.
I used it on the MKIII .303 and it still is not clean after 3 rounds of this stuff. But you can see a lot of progress in the bore's appearance. It also removes powder and lead fouling as well. The .303 was made in 1908. I believe the fouling dates back that far as well!!
Good shooting everyone. I go back to work tomorrow :eek: after 10 days off. The only good news is I am back on the day shift tomorrow as well.
