I found mine did that much quicker when using grease instead of oil. It took 32 years and 50,000+ rounds to show half that much wear on the jewelling of my 101 using oil and only a few hundred rounds using grease on my 725. I no longer use grease. I went back to oil. RemOil to be specific. I like that stuff best of all. Been using it as long as I can remember.
