About 5 years ago, I got onto the moly-coated bullet bandwagon. A year later, I was off the bandwagon. However, in the case of Barnes X bullets only, I still tumble them in moly and rub them down hard before loading them. Keeping the moly from building up is easier on the barrel than removing the copper fouling caused by these bullets. I get a lot of black out of the barrel instead of a lot of blue. Moly has it's own set of problems, but it does cut way down on copper fouling. I haven't tried the Triple Shocks yet, but intend to do the same thing with them.
Sweets 7.62 and the Barnes copper solvent are aggresive enough that I immediately cleaned behind them with # 9. That just increased the number of cleaning rod passes to an unacceptable level for me.
This is not a recommendation, just my conclusion.
