Anybody have experience with any of the foaming bore cleaners ? I've tried the Break Free brand foaming cleaner and was not impressed with it's copper removal. It took some out, but further Sweets 7.62 applications were needed to finish the job. Sweets took much more copper out of the barrel before it was down to bare metal. The Break Free was very expensive and I'm looking for others experience with the any of the other brands before I decide to buy or not to buy.
Thanks.
Mike
