Interesting thread. I just returned from a trip to my basement, where I read the labels on Shooter's Choice, Sweets 7.62, Klenzoil, Breakfree CLP, Remington bore cleaner. All of them claimed to REMOVE lead, carbon, copper and plastic fouling. NONE of them claimed or even hinted at DISOLVING lead. It would be interesting to know where the solder attacking stories get started. Least likely is from provable personal experience. I've heard Hoppe's #9 blamed for causing nickel plating to come off old revolvers, over the years. That seems highly unlikely to me, as well. SMLE Kid's idea on why ribs come loose at the front and rear makes far more sense to me than some bore cleaner being at fault.
