Chantecler - I have not, so far, tried the foam. It sounds pretty good from the advertisements, though. Sweet's 7.62 has worked for me so well over so many years that it would be tough (although not impossible) to switch at this point. Does the foam have the very strong ammonia smell?
I personally, quite using the foam, in favor, of more conventional cleaning methods, like Hoppe's No. 9, and Barnes CR-10, the foam, did lack the smell of ammonia, but, it did seem to dissolve copper very good, when left in the bore for an hour or more.
