I haven't used them since I stopped shooting moly. I only stopped shooting moly because I was changing components too fast and it took too long to coat so many different bullets in small batches.
For me, moly only stopped the copper fouling in aftermarket barrels, my factory barrels were too rough. It did, however, seem to slow throat wear a lot. An example .. I had a .220 Swift in a 700 VSSF which I put over 2000 rounds through, all moly coated bullets. I assumed it was about used up so I consigned it to buy something else. A few days later the store owner and a perspective buyer called me to ask what was wrong with the gun. To their eye with a bore scope it looked like less than 200 rounds worth of wear, not 2000 .. and I was running a fairly hot load of 43.5 grains of H380 under 50 grain ballistic tips. I am convinced it works for extending barrel life even if it is not reducing fouling.
