I have always meant to try Barnes CR-10, since the Barnes bullets, I shoot like to
put copper in the bore. But I found Montana Xtreme Copper Cream, in the Sinclair
catalog, and gave that a try. It works well, in liberal applications, on fouled barrels.
According to the label, it works on copper, lead, and powder fouling, as well as shotgun
wad plastic fowling. I had a fairly heavily fouled BAR barrel from shooting Barnes
X bullets, and with two or three liberal applications of this cream, in the bore, and a
good scrubbing with a plastic bore brush, all of the copper was gone, along with
all of the other forms of crude, in the bore. This stuff is non-embedding, non-abrasive
to metal, and is recommended for new barrel break-in. I probably won't be trying
Barnes CR-10, after finding Copper Cream.
